hi there, I got my TN last July and filed perm last Nov, still pending. I am thinking submit a h1b on April, but not sure if perm would affect h1b? ( since it shows immigration intention) and since h1b can't start until oct 1, I need to renew tn on July, does h1b application/approval affect my tn renew? last question is how will the 6 year of h1 be calculated, does it start oct 1,2006 or start July, 2005. Thanks.
