[USAVIS]

Friends,

I need all your inputs, suggestion on H1B stamping question.

Here are my details..

1. H1B Extn filed while working with Client-A in 2012 Jan. Got approval until 2015 Jan.

2. Moved to client-B from Apr 2012 - July 2012. Only 3 months. Employer filed new LCA. But he didnt ammend the H1B as the distance from client-A & Client -B is 20 miles.

3. While working Client -B, USCIS officer visited Client-A to ensure I am working for them. He was not able to trace me as I moved to Client-B. USCIS officer sent an email to my employer asking my details. Employer replied back with Client-B details, New LCA, Pay stubs. USCIS officer is happy with those.

4. In August-2012, moved back to client -A and employer filed new LCA

5. I am planning to go for H1B stamping as my client is ready provide client letter.

here are my questions which are needed your valuable suggestions, Inputs.

1. My I-129 contains, Client-A information. If visa office asks when you joined current client, what should i answer?

2. Can i answer without mentioning Client-B details?

Plese advise me.
