在已更換過雇主的情況下， 請問沒過期的多次往返的H1簽證是否可再用？
-Yes, but you need to show your current H1 approval notice (new emloyer sponsored) and the recent 3 month paycheck stubs to the CBP officer at the port of entry when you return and double check the I-94 to make sure the new H1 I-94 duration matches the new H1 approval notice duration (same effective time length). If no, ask the officer to fix it immediatelt on face to face.
