5 Hidden Costs in Immigration Legal Contracts (and How to Spot Them)

An employer signs a flat fee for an H-1B petition. When a Request for Evidence arrives, the response might fall outside of that fee.

That added cost isn't necessarily improper. The surprise comes because the contract failed to explain the limits of the original scope.

Three separate things sit inside almost every immigration matter, and keeping them apart explains most of the surprises:

1. There is the attorney fee, which is what the firm charges for its own work.
2. There are government filing fees, which are set by USCIS and paid to the agency, and which can run larger than the legal fee.
3. And there are costs, the third-party disbursements like translation and credential evaluation that the firm advances and bills back.

A flat fee prices a defined scope of legal work. It does not cover everything a case can require, and it never covers the government fees.

Bar ethics rules generally allow a firm to charge for something as long as it is both disclosed in advance and reasonable, which means the costs that catch employers off guard are usually the ones the agreement left vague didn't cover. This guide walks through where those costs live in a legal contract and why each one arises. The rules referenced are general and current as of July 2026; how any of them applies to a specific case is a question for counsel.

What a Law Firm Engagement Agreement Actually Contains

The contract that opens a case goes by a few names (an engagement letter, a retainer agreement) and follows a fairly standard structure. Reading it with that structure in mind is what makes the five costs below easy to locate.

• Scope of representation. This section defines what the firm will do and, where it is written well, what it will not do. It is the section that matters most for cost, because anything outside the defined scope is billed separately.
• Fee structure and amount. The fee is stated as a flat amount, an hourly rate, or a hybrid of the two. Bar rules ask that the basis of the fee be communicated to the client, and many states require that in writing.
• Costs and expenses. Separate from the fee, this covers third-party disbursements the firm advances on the client's behalf, such as translation, credential evaluations, couriers, and any government fees the firm remits.
• Retainer and trust terms. If the firm takes money up front, this explains how it is held (client funds sit in a trust account until earned) and how the balance is drawn down and, in some agreements, replenished.
• Additional services and termination. One clause addresses work that falls outside the original scope, and another addresses what happens if either side ends the relationship, including how the file is handled.

1. RFE Responses and Appeals Billed on Top of the Flat Fee

A flat fee prices the preparation and filing of the initial petition. A Request for Evidence, which USCIS issues when it wants more documentation before deciding, is unpredictable additional work, and an agreement may exclude the response or include only one round.

An appeal or a motion to reopen after a denial (filed on Form I-290B, with its own government fee) sits even further outside the base scope. If the agreement doesn't cover them, the additional legal and government fees can come as a surprise.

• Where it lives in the contract: the scope-of-representation section and any "additional services" clause. Whether an RFE response is inside the flat fee or billed separately is a written-scope question, not an assumption to carry in.
• Why it arises: the cost of an RFE cannot be known when the fee is set, so firms price the predictable part and treat the unpredictable part as extra. A case flagged as likely to draw an RFE may carry more upfront work, and a different fee, for that reason.

2. Extensions, Amendments, Transfers, and Dependents Treated as New Cases

A flat fee is priced per petition, not per employee for the life of their employment. An extension when the visa term ends, an amendment when the job or worksite materially changes, and a transfer when the worker moves to a new employer are each generally a fresh petition on a new Form I-129, with its own legal fee and its own government fee.

Dependent filings sit in the same category: a spouse or child on H-4 or L-2 status files a separate application (Form I-539) that carries its own government fee and a legal fee that is generally quoted separately. An employer budgeting for "an H-1B" sometimes budgets for one filing and then meets the full lifecycle.

• Where it lives in the contract: the scope section, which typically names the specific petition being handled rather than the employee's entire immigration journey.
• Why it arises: each of these steps is a distinct government filing with its own adjudication, so the work does not fold into the original petition. Dependent legal fees also fall outside the employer's required costs under federal rules, which is why they are frequently quoted, and sometimes paid, separately.

3. Costs and Disbursements: Pass-Throughs, Markups, and Surcharges

Beyond the attorney fee and the government fee, a case generates third-party costs: certified translation of foreign documents, a credential evaluation to map a foreign degree to a U.S. equivalent, a medical exam for a Green Card, couriers, and similar out-of-pocket items. A firm advancing these and billing them back at cost is standard.

Two things are worth understanding.

First, under ABA Formal Opinion 93-379, a firm generally should not mark a disbursement up above its actual cost unless the client agreed to that in advance or the firm actually incurred additional costs beyond the disbursement itself.

Second, general office overhead (the kind of thing built into a rate) is not meant to reappear as a separate "administrative," "technology," or "processing" surcharge unless the agreement disclosed it.

• Where it lives in the contract: the costs-and-expenses section, which should describe which items the client pays and whether they are billed at cost or at a set rate.
• Why it arises: disbursements are real expenses, so passing them through is expected. The surprise is usually in the size or the labeling, and the agreement is where a per-page rate or a flat cost charge is either disclosed or left open.

4. Government Fees and the Rules on Who Legally Pays

In an employer-sponsored case, the government fees can exceed the legal fee. Government filing fees are set by USCIS, change on their own schedule, and are the employer's to pay on employer petitions.

They can also rise: premium processing rose to $2,965 for most I-129 classifications effective March 1, 2026, and other charges have been introduced and challenged in court.

Because these are separate from the legal fee, an employer working off last year's total can be caught short when these figures change.

Who pays is also constrained by law, not just by the contract. For H-1B petitions, the Department of Labor treats the attorney fees and filing fees as the employer's business expense, and the ACWIA training fee and the $500 fraud fee can never be charged to the worker.

For PERM labor certification, the rule is firmer still: the employer must pay every cost, including its own attorney fees and the recruitment expense, and the employee cannot pay or reimburse any of it (the one exception being an employee's own separate attorney, where the employee has independent counsel). An engagement agreement cannot lawfully shift those costs onto the employee, and getting the allocation wrong is its own exposure: for H-1B, back wages, civil penalties, and possible debarment; for PERM, denial, revocation, or debarment of the labor certification.

• Where it lives in the contract: the fee and costs sections should separate the legal fee from the government fees, and a program agreement may address how fee changes are handled mid-engagement.
• Why it arises: government fees are outside the firm's control and change by rulemaking, so a flat legal fee quoted cleanly can still sit next to a government total that has shifted. The details of who pays a given fee are fact-specific and worth confirming with counsel before relying on any split.

5. Retainer and Exit Terms: Replenishment, Minimums, and File-Release Charges

The mechanics of how a firm bills, and what happens when an engagement ends, are set in the contract and can carry costs an employer does not anticipate. An evergreen retainer requires the client to top the trust balance back up whenever it falls below a set minimum, which is an ongoing obligation rather than a one-time deposit.

A hybrid arrangement that bills hourly for anything outside the flat scope may apply minimum increments or rounding to calls and emails, which is permissible when the agreement states it. And on the way out, termination and file-handling terms govern what it costs to move a matter to a new firm, though the client file generally belongs to the client.

• Where it lives in the contract: the retainer and trust section for replenishment and billing increments, and the termination section for file handling.
• Why it arises: these terms are routine and enforceable when disclosed, so they are less about anything hidden and more about reading the parts of the agreement that describe the ongoing and end-of-relationship obligations, not just the headline fee.

How Manifest Prices Immigration Work

Manifest Law bills corporate immigration work as a flat per-case fee with no hourly billing, and that fee is quoted separately from the government filing fees an employer owes, so the two are itemized rather than blended into a single number. Corporate pricing is quoted per program rather than as a published consumer rate, because the right structure depends on how many cases an employer files and which visa types are involved. For how the underlying numbers break down, see Manifest's guides to H-1B attorney fees and H-1B costs for employers.

Frequently Asked Questions

What is the difference between attorney fees and government filing fees?

Attorney fees are what a law firm charges to prepare and file a case, and they vary by firm and complexity. Government filing fees are set by USCIS, paid to the agency, and fixed by a published schedule. They are separate charges paid to different places, and on employer petitions the government fees frequently run larger than the legal fee.

Are Request for Evidence responses usually included in a flat fee?

It depends entirely on the agreement. Some flat fees include one RFE response and some exclude it, billing the work separately when it comes up. Because an RFE is unpredictable additional work, whether it is covered is defined in the scope section of the engagement letter rather than assumed.

Can a law firm mark up costs like translation or courier fees?

Under ABA Formal Opinion 93-379, a firm generally should not charge more than the actual cost of a third-party disbursement unless the client agreed to a different arrangement in advance or the firm incurred additional costs beyond the disbursement itself. Passing costs through at cost is standard. A markup or a separate administrative surcharge is a matter that should be disclosed in the costs section of the agreement.

Can an employer make the employee pay immigration legal fees?

For H-1B and PERM sponsorship, generally no. The Department of Labor treats the petition attorney fees and filing fees as the employer's expense, and certain fees such as the ACWIA training fee can never be shifted to the worker. Because the rules are fact-specific and carry real penalties, the allocation is worth confirming with counsel, and the Labor Condition Application is where the H-1B wage and fee obligations are set.

How can I tell what a legal fee actually covers before signing?

The answer is in the scope, fee, and costs sections of the engagement agreement. Those sections define what work the flat fee includes, what is billed separately, and how third-party costs are handled. Anything a case might require that is not addressed there is where an unexpected charge can appear later.
