I am changing the employer from A to B. Employer B is applying for H1B transfer using premium processing. My wife is in India. Her visa stamping is based on old employment. I have two concerns.
Do I need to apply for her H4 transfer even though her current H4 is valid for next 1.5 years?
Can I join new employer (15 days) before my wife arrives in USA?
Thank you in advance for your help.
