I applied the B1/B2 visitor visa while I was holding a Temporary Worker Permit in Canada about 10 months ago, and the B1/B2 Visa ,which I had been issued, has expiration date on 2011-Aug.
However, I have recently been granted as a Permanent Residence status in Canada, and my B1/B2 visa to USA hasn't been expired as the date stated on the card (2011-Aug
My questions are:
1.Could I travel to USA without renew my B1/B2 visitor visa before the expire date ?
2.Do I need to inform USA Embassy for updating this changing status in Canada(From Temporary worker to Permanent Residence)?
