H1B， I485 pending, AP approved, working as a Research Associate at a Univeristy.
1. If go back China and come back with AP, will I lose my H1B status if I still work for my University, or I will only have I485 pending status?
2. If go back China and apply H1B visa, but not approved, is it ok to use AP to come back?
3. How to apply H1B visa in Chengdu, still can contact 中信实业银行，预约吗？if so, no interview is needed, right? where can I get the contact info. of 中信实业银行?
4. Is it possible to get background checked?
5. What documents do I need to apply H1B visa;
1.Money (how much, in RMB?)
2. Passport
3. ? form for H1B visa application
4. H1B approval I797 (copy? or original?)
5. Employment verification letter
