The number on the first page of a retainer is the least informative thing in the document. Two attorneys can quote the same figure for the same petition and mean entirely different amounts of work, and the difference sits four pages back, in the paragraph headed scope of representation. A careful reader spends most of their time there, and on the sentence that lists what the fee excludes. The rest of the agreement, the termination clause, the file retention terms, the arbitration language, matters too, but scope is where money is won and lost.
Scope is a list of filings, not a description of a goal
A well-drafted scope clause names the specific forms and the specific stage. Preparation and filing of one I-130 petition, with supporting documents, through adjudication by the agency. That is a scope. Representation in your immigration matter is not a scope, it is a mood, and it will be read narrowly the first time something unexpected arrives. Ask which forms are covered by number, whether derivative family members are inside the fee or each carry their own charge, and what happens if the case shifts categories midstream. If the answer is vague in conversation, it will be vaguer in a dispute.
The second thing to look for is the endpoint. Some agreements end at filing, which means the receipt notice is the last thing the office does for that fee. Others run through a decision, which is a materially larger commitment because it absorbs whatever the agency asks for in between. A request for evidence can take a week of drafting and a stack of new documents, and whether that week is included or billed separately should be stated in a sentence you can point to.
Government filing fees are not the attorney's money
Filing fees go to the agency, and a competent agreement says so plainly, lists the current amounts as of the signing date, and notes that they are set by the government and subject to change. Biometrics, medical exams performed by a designated civil surgeon, consular processing charges, certified translations, courier costs and civil document retrieval from a foreign registry are all outside the legal fee in most retainers. None of that is hidden or improper. What matters is whether the total you are budgeting for includes them, because a quote that sounds two thousand dollars cheaper often just moved those costs into a footnote.
Denials, refilings, interviews and appeals
Ask what happens if the case is denied. The honest answers vary: some offices refile once at no additional fee where the denial was not caused by new facts, some charge a reduced rate, some treat a refiling as an entirely new matter at full price. Any of those can be reasonable, and all of them are better than silence in the document. The same question applies to interviews. Attendance at an adjustment interview or a consular appointment is a discrete block of preparation and time, and it is routinely quoted separately, so confirm which side of the line it falls on before you assume.
Appeals and motions almost never sit inside a flat fee, and you should be suspicious of an agreement that implies otherwise. A motion to reopen, a motion to reconsider, an appeal to the Administrative Appeals Office or the Board of Immigration Appeals: each is a separate proceeding with its own filing fee, deadline and brief. Expect a separate engagement letter and a separate number. The Department of Justice, through its Executive Office for Immigration Review, is responsible for recognizing organizations and accrediting the non-attorney representatives who may appear in those forums, which is worth knowing when you compare providers.
When hourly billing is the straighter answer
Flat fees work when the work is predictable. For removal defense, complex waivers, cases with criminal history or long gaps in status, and anything with an unpredictable litigation tail, an hourly agreement with a clear rate, a stated billing increment and a replenishing retainer is often the honest structure, because a flat fee for unpredictable work is either padded to cover the worst case or too thin to survive it. Ask for monthly statements with task descriptions, ask what the increment is, and ask who else in the office bills to your file and at what rate.
The questions that move the number
Ask what is excluded, in a sentence. Ask what a request for evidence costs. Ask whether the interview is included, whether a second interview is included, and what a denial triggers. Ask whether payment can be staged against milestones rather than paid up front, and whether the unearned portion is refundable and how that is calculated. Ask for the written answers. Offices that quote carefully tend to welcome the questions, and the conversation itself usually tells you which quote you are actually comparing.
