Surname Blank in passport

I am applying for H1B and my surname is blank in passport.

  1. Will it make any issues in the process ?

  2. Will I get a petition , then how the name details will display ?

  3. Planning to update the surname if petition got approved. [ Currently I don’t have time change surname and submit H1]

It wont create any issue with process per say. US visa needs last name. In case you don’t have last name, they will use your first name as last name and firs name will be unavailable (FNU). So if you name is Kumar, according to visa your name will become FNU Kumar.

Issue is when you to US, they will use the same name (FNU Kumar) everywhere (your SSN, DL, all other legel documents.
