Why the client letter question comes up
The visa officer asks about a client letter because H1B roles often involve working at a third-party client site. If you cannot show who you are working for, the officer may question whether your role and placement are genuine. But not every H1B position works that way — and if yours does not, you need to be ready to explain your situation clearly and back it up with the right documents.
Three situations where you may not have a client letter — and what to do
1. You are working on in-house projects for your U.S. employer
Your work may have nothing to do with an external client at all. You could be supporting your U.S. employer's own internal processes, systems, manufacturing facility, or warehouses. In this case, there is no client to provide a letter — because your employer is also your end client. Explain this clearly to the visa officer and carry a supporting letter from your U.S. employer that states you are working on internal projects for the company itself.

Book a Mock Interview2. You work for a client but not at the client's location
You might be assigned to a client project, but your actual day-to-day work does not require you to be physically present at the client's site — and you may have no direct interaction with the client at all. The requirements of the project are handed to you, and you execute that work from your company's own office. This is a legitimate arrangement, and you can explain it to the officer. What you should carry in this case is a statement of work that describes the project and confirms your work location.
3. You work in a sensitive domain where clients do not share their details
If your role is in a sensitive industry like banking or insurance, many clients in these sectors are simply not comfortable providing a client letter or disclosing their details to third parties. This is a well-known constraint in those industries, and it is something you can explain directly to the visa officer. To support this, carry a letter from your U.S. employer that acknowledges the nature of your domain and confirms why a client letter is not available.
The key takeaway
Not having a client letter does not mean your case is weak. What matters is that you have a clear, honest explanation for your situation and that you back it up with the right paperwork — whether that is an employer support letter, a statement of work, or a domain-specific explanation letter. Go into the interview knowing exactly which of these three situations applies to you, and have your documents organised and ready to present.

Komal moved to the USA in 2022 on an H1B visa — with her young daughter in tow and her husband already in the country on an L1B.

How do I answer 'What will be your role in the US?' at my H1B visa interview?
One question trips up almost every H1B applicant at the visa window: 'What will be your role in the US office?' The way you answer it determines whether the officer moves on — or opens the door to a long chain of follow-up questions.
