The REF requests me to submit my I-94 AND IF applicable, include a copy of all petition / application approval notice (Form I-797) issued to you by this service granting extensions or changes of Nonimmigrant status.
My question is do I need to submit every approval notice I have so far, for example from F2 to F1, from F1 to H1B, and H1B transfer and H1B extension?
Pjiang answered my question saying I need to submit "whatever since my last admission". I did not change or extend my nonimmigrant status since my last admission. I extended my H-1B last year BEFORE I went back to China and used that approval notice to get a new VISA to enter U.S. If I understand Pjiang right, I do not need to submit any approval notice since I do not have any new approval notice since my last admission?
Thank you thank you for answering my questions!
