My fiance is currently in USA. We are trying to obtain a H1 visa for her. With the qualifications and experience she is eligibile for a H1 visa sponsorship.

Has any of you guys gone through this process before of converting from B1 visa to H1 status? Can you provide some advise on this issue? what all issues should I be careful of when going through this process?

Thanks in advance for your help and advise.
