I have a question regarding use of AP. Here's the situation.. I have been on H1B (valid till 2004) visa (my H1 visa on passport expired) ,
--- You can get H1 visa stamp from your home country and can re-enter on H1, you are visiting Canada take the appointment and you can also get your H1 visa stamped, you will be able to collect the passport with Visa nest day of interview, if you still want to use AP that is up to you.
Currently I am waiting to receive AP after filing AOS. My wife who has valid H4 visa on passport has left US after filling AOS, and will return after few months.
--- She can return on H4 visa, after filing AOS (she should enter US before her H4 Visa in passport expire, as She has no AP with her,
My question is if I use AP after visiting Canada before the return of my wife and continue working with my existing employer. Will that invalidate my wife's H4 visa and/or would she face any problem when she will return to US after few months?
If you go to Canada and use AP to re-enter US, it will have no effect on her H4, you should NOT use EAD till she is back on H4, once the primary applicant uses EAD for work then you are no more on H1 status, just using the AP will not invalidate your H1 status if you are working with the same employer and maintain H1 status your wife can enter on H4.
