回复：Help. Should I Go to Canada to Get Visa?

you should first check if new aproved notice with new I-94. If there is no new I-94 in the lower part of letter, you should go out country and come back. as canadian citizen, you do not need visa and apply H1-B status in port of entry. by the way, your lawyer should be fired.
