The question people usually ask is what an attorney charges. The more useful question is what the wrong answer costs, because those two numbers have almost nothing to do with each other. A naturalization application filed with a careless answer might cost a denial and a second filing fee. A green card application filed by someone who left the country during an overstay can cost a decade of separation, and no amount of money spent afterward buys that time back. Sorting cases by what a mistake actually does is the only sorting worth making.
The cases most people really can file alone
Straightforward naturalization sits at the easy end. If you have held a green card for the required years, have not spent long stretches outside the country, have no arrests, have filed your tax returns, and registered for Selective Service if that applied to you, the form is long but it is not a puzzle. United States Citizenship and Immigration Services, the agency responsible for adjudicating these petitions, publishes the instructions and the civics questions in full. Plenty of people complete it at a kitchen table with a folder of documents and get sworn in without ever speaking to a lawyer.
A marriage-based adjustment of status with no complications belongs in the same category, though it is a heavier lift. Adjustment of status simply means applying for a green card without leaving the country. If the citizen spouse can meet the income requirement or has a willing joint sponsor, if the immigrant spouse entered lawfully and was inspected at a port of entry, and if neither person has a criminal record or a prior immigration history, the packet is a matter of assembling evidence carefully and answering honestly. The interview asks about the marriage, not about law.
Where a single answer can close the door
Three facts change everything, and any one of them should stop a self-filing plan before the first form is printed. A prior removal or deportation order, even an old one entered when you did not appear in court, follows a person and can trigger a bar of five, ten, or twenty years. A criminal record, including a case that was dismissed, deferred, or expunged under state law, may still count as a conviction for federal immigration purposes. And unlawful presence, accrued after a visa expired, can create a bar that only becomes active the moment you leave the country.
What makes these situations dangerous is that the danger is invisible from the outside. The form does not warn you. It asks a question, you answer it truthfully, and the answer either surfaces a problem you could have prepared for or triggers one you could have avoided. This is the point at which paying an Immigration Lawyer for a consultation, even a single paid hour with your court records in hand, buys information you cannot get anywhere else. The consultation might confirm you are fine. It might also change the entire sequence of what you file and when.
The middle band, where it depends on the facts
Consular processing, meaning the spouse or relative is abroad and will be interviewed at an embassy, is harder to unwind if it goes wrong, because a refusal happens in another country and the person is not standing next to you. Employment-based cases turn on job descriptions and wage levels that are technical without being legally dramatic. Waivers of any kind, including the provisional waiver for unlawful presence, are argument documents rather than forms, and they are graded on whether a qualifying relative would suffer hardship. Those are worth paying for, because the writing is the case.
Fee waivers, humanitarian filings, and anything with a deadline attached also sit here. So does any case where the sponsor's income is close to the threshold, where the marriage is recent and the paper trail is thin, or where a previous application was denied and you never learned exactly why. None of these are automatic disqualifiers for handling things yourself. They are simply the situations where an hour of paid review before filing tends to be the cheapest money in the whole process, measured against what refiling costs.
Counting the cost honestly
Government filing fees are owed either way and are not refunded when a case is denied. Add to that the time value: a denial on a straightforward case usually means months lost, while a denial that creates a bar means years, and a case that puts someone into removal proceedings means a different kind of expense entirely. Set the legal fee against the version of the outcome you are actually trying to avoid, not against the version where everything goes smoothly. The comparison is uncomfortable but it is the correct one.
It also cuts the other way, and honestly. Paying four thousand dollars to have someone assemble a naturalization packet you could have assembled yourself is money that bought reassurance rather than legal work, and reassurance is a real thing to want but it should be priced as what it is. The useful middle is a paid consultation, a written scope of what the office will do, and a clear answer about who handles the interview.
What the rest of this site sorts out
The remaining pieces here work through the mechanics: how to read two quotes that name the same number for different amounts of work, how to check that the person advising you is actually authorized to do it, what a flat fee typically includes and excludes, what happens to your money and your file if you change offices midway, and what to do when a case is already filed and something has gone sideways. All of it assumes you are spending your own money and want to know exactly what for.
Start by writing down the three facts that matter: how you entered the country, whether you have ever been arrested or fingerprinted anywhere, and whether you have ever been ordered to leave. Those answers decide which column your case belongs in, and everything else follows from there.
