A family invitation letter for a US visa is a document you write as the U.S.-based host to support a relative’s B-2 visitor visa application, giving the consular officer a clear picture of who is visiting, why, for how long, and who is covering the costs. It is not a legal filing and it does not decide the case. It fills in context the DS-160 form cannot carry on its own, especially the personal side of the relationship and the concrete plan for the trip.
Is the Letter Actually Required
No. Federal regulations and the State Department’s own guidance do not list an invitation letter among the required documents for a B-2 visa, and consular officers have said the same.1U.S. Department of State. Visitor Visa Applicants get approved without one every day. The letter earns its place when the applicant’s own finances are modest, when they’ll be staying in your home rather than a hotel, or when the family connection isn’t obvious from the paperwork. If your relative has a strong travel history and clear finances, the letter matters less. For a first-time applicant on a tight budget, it matters quite a bit.
What to Put in the Letter
Treat the letter as answering the questions a consular officer would ask if they could call you: Who are you? Who is your relative? How are you related? What will they do here, and for how long? Who pays? Every sentence should serve one of those.
Your Information as the Host
Open with your full legal name as it appears on your U.S. passport, Green Card, or other immigration document. Give your home address, phone, and email. Say whether you are a U.S. citizen, a lawful permanent resident, or the holder of a valid work visa. The officer needs to see that you are legally present and reachable.
Your Relative’s Information
Provide the visitor’s full name, date of birth, passport number, and home address abroad. Spell the name exactly as it appears on the passport. A small mismatch between your letter and the DS-160 creates doubt you don’t want to introduce.
The Relationship
State the family connection plainly. “She is my mother.” “He is my brother.” “They are my aunt and uncle.” If the link isn’t provable from a single birth or marriage record, explain briefly. A cousin relationship, for instance, may need a sentence noting that your parents are siblings.
Trip Details
Give the arrival and departure dates your relative plans to travel, and name a concrete reason for the visit. “Visiting family” tells the officer nothing. “Attending my daughter’s college graduation on May 15 and staying through May 25” gives them something to evaluate. Weddings, reunions, and religious ceremonies are worth naming. The more specific the purpose, the more credible the temporary nature of the trip.
Financial Responsibility
This is the part that carries the most weight. If you are covering airfare, housing, meals, or other costs, say so directly. If your relative is paying their own way and you are only providing a place to stay, say that instead. A vague offer to “help out” tells the officer nothing useful. Officers want to see a concrete plan so the visitor won’t need public assistance, which ties directly to the public charge ground of inadmissibility that lets a consular officer deny a visa when the applicant is likely to depend on government benefits.2Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens
What to Leave Out
The wrong phrasing can actively hurt the application. A few lines to avoid:
- “I guarantee they will return home.” You cannot guarantee another person’s behavior, and the officer knows it.
- “They can stay as long as they want.” Open-ended invitations contradict the requirement that a B-2 visit be temporary with a defined end.
- “They can help with my business while they’re here.” Any mention of work, paid or not, raises a flag. B-2 visitors are not permitted to work.
- “I will take full responsibility for them indefinitely.” Overpromising undercuts credibility. Officers prefer specific commitments tied to the dates of the visit.
Keep the tone honest and specific. You are providing context, not making a legal argument. A letter that sounds like it is trying too hard often has the opposite effect.
How to Lay the Letter Out
You don’t need a lawyer to write this. A clean formal structure works:
- Header with your full name, U.S. address, phone, and email; below that, the date and the name and address of the U.S. embassy or consulate where your relative will interview.
- Salutation: “Dear Consular Officer” or “To Whom It May Concern.”
- Opening paragraph stating your name, immigration status, and that you are inviting your relative (full name) to visit on specific dates.
- Relationship paragraph explaining how you are related and why you want them to visit.
- Trip paragraph describing what you’ll do together, where your relative will stay, and any events planned.
- Financial paragraph spelling out who is paying for what.
- Closing statement acknowledging that the visit is temporary and that your relative intends to return home by the departure date.
- Your handwritten signature, printed name, and the date.
Write in English. Keep the letter to one page. Officers work through many applications in a day, and a concise letter gets read more carefully than a three-page essay.
Documents to Attach
The letter gains weight when the claims in it are backed by paper. At minimum, send:
- Proof of your legal status: a copy of your U.S. passport, Green Card, naturalization certificate, or valid visa.
- Proof of your finances: recent bank statements or pay stubs from the last two to three months. The officer is looking for stability, not wealth.
- Proof of housing if your relative will stay with you: a copy of your lease or property deed.
- Proof of relationship: birth certificates, marriage certificates, or family records that connect you and your relative.
Send copies, not originals, of your own documents. Your relative brings those copies to the interview alongside their own originals.
When Form I-134 Is the Better Tool
If your relative’s finances are thin, a letter may not be enough. Form I-134, the Declaration of Financial Support, is a formal document on which you agree to support your relative during the visit and sign under penalty of perjury.3U.S. Citizenship and Immigration Services. I-134, Declaration of Financial Support That legal weight is why some consular posts treat it more seriously than a self-drafted letter.
The form isn’t required for most B-2 applications, but an officer who is concerned about public charge can ask for it. You’ll document your income, assets, and employment on the form. There is no fixed income threshold written into the form itself, but officers often compare household income against the federal poverty guidelines.
Matching the Letter to the DS-160 and the Interview
The visa decision rests primarily on your relative’s ability to convince the officer that they will leave the U.S. when the visit ends. Federal law presumes every visa applicant intends to immigrate permanently, and the applicant has to overcome that presumption.4Office of the Law Revision Counsel. 8 USC 1184 – Admission of Nonimmigrants Officers weigh whether the applicant has a residence abroad they don’t intend to abandon, whether the stay is for a limited time, and whether the purpose is a legitimate temporary activity.5U.S. Department of State. 9 FAM 402.2 – Tourists and Business Visitors and Mexican Border Crossing Cards Your relative should bring evidence of ties to home: an employment letter, proof of property, savings, or family members who depend on them. Those documents matter more than your invitation letter does.
The DS-160 itself asks who is paying for the trip and requires a U.S. point of contact. The answers there should match your letter exactly. A mismatch in dates, spelling, or financial arrangements is hard to walk back in a short interview. The nonrefundable application fee is $185.6U.S. Department of State. Fees for Visa Services
Once you’ve signed the letter and gathered the documents, send the package to your relative so they have the originals for the interview. If mailing time is tight, a clean scanned copy printed on their end is better than arriving with nothing. Your relative should stack the invitation letter on top, your supporting documents next, and their own personal documents underneath.
If the Visa Is Denied
A refusal under Section 214(b) is the most common outcome for a denied B-2. It means the officer wasn’t satisfied that the applicant overcame the presumption of immigrant intent or otherwise qualified for the category.7U.S. Department of State. Visa Denials It is not a permanent ban. There is no formal appeal, but your relative can reapply by submitting a new DS-160, paying the fee again, and scheduling a new interview.
If the last denial turned on an unclear financial picture, that is where your letter can do real work on the next attempt. A more specific invitation letter with better documentation, or a Form I-134 backed by solid proof of income, speaks directly to the officer’s concern. Reapplying with identical paperwork and hoping for a different officer is not a strategy; prior refusals are visible in the system.
