I have to back to Vancouver to change new China Visa(old one expire date is 4/31/08), then I need apply a usa visa back. The question is :
1) May I apply usa visa using my old visa ID number(it's diffrent with new one)? So I can save the time ,don't need staying Canada a couple of months for waiting the usa visa.
2) Do I have to be Vancouver China Embassy by myeslf to change my new chine visa, mail to there is it ok?
Thanks
