Two offices can quote the same family-based petition and produce numbers that look nothing alike, not because one is cheap and one is greedy, but because the two documents draw the boundary of the work in different places. One quote may fold in the interview, the second may treat the interview as a separate engagement, and neither is hiding anything if you read the whole page. The difference lives in the scope paragraph, which most people skim, and in the exclusions paragraph, which most people never reach. A careful reader goes to those two paragraphs first and works backward to the number.
Legal fees and government fees are not the same money
Every honest quote separates what the office charges for its time from what the government charges to accept a filing. The legal fee compensates the attorney or the accredited representative for preparing forms, assembling evidence, drafting a cover letter, and answering the agency when it writes back. The filing fee goes to U.S. Citizenship and Immigration Services and is set by the Department of Homeland Security, which is responsible for the fee schedule and for the categories of applicant who may request a fee waiver or a reduced fee. Biometrics, where a case requires them, may be billed separately or bundled into the filing fee depending on the form. A quote that gives you a single number with no split is not necessarily wrong, but you should ask for the split in writing before you pay anything.
Flat fee, hourly, and staged: three ways to buy the same work
Private offices most often quote a flat fee per form or per case, which gives you certainty about the total and gives the office an incentive to work efficiently. Hourly billing appears more often in removal defense, in complex waiver work, and in cases with an unpredictable litigation path, and it should come with an estimated range, a billing increment, and a statement of who bills at what rate. Staged pricing splits the case into phases, with a payment due as each phase opens. Nonprofit and recognized organizations, whose accredited representatives are approved by the Executive Office for Immigration Review, typically charge modest flat fees or sliding-scale fees tied to household income, and their agreements tend to be shorter, though the scope questions you ask should be identical.
What 'through approval' and 'excludes appeals' actually cover
The phrase "representation through approval" sounds like an end-to-end promise, and it usually means something narrower: the office will handle the filing and the ordinary correspondence until the agency grants or denies the specific benefit named in the agreement. It rarely includes a second, related filing that the approval makes possible, such as the work permit that follows a pending application or the removal of conditions two years after a marriage-based green card. "Excludes appeals" is the companion clause, and it generally sweeps in more than the word appeal suggests: a motion to reopen, a motion to reconsider, a federal court action, and sometimes an appearance before an immigration judge. Ask which of those four the sentence is meant to cover, and ask for the answer to be added to the document.
The stages that commonly produce a second bill
A request for evidence is the most frequent trigger, because responding to one can take as long as the original filing, and agreements differ on whether the response is included, capped, or billed anew. A notice of intent to deny sits a step further along and almost always falls outside a basic flat fee. Interviews are the next dividing line, since attendance at a USCIS interview, an adjustment interview, or a consular follow-up may be inside or outside scope. Refiling after a denial, a change in the client's circumstances that alters the eligibility theory, and a translation or medical exam that the office arranges rather than performs are all worth a direct question. Get the answers before signing, and the agreement becomes a map rather than a surprise.
The comparison that matters, then, is not between two totals but between two scopes measured against the same case. Write down the stages your case is likely to pass through, ask each office to mark which stages its number covers and what the rate is for the rest, and the quotes become comparable in a way the headline figures never are.
