First time @Shanghai. F1->H1B
@3rd week email them, told me: the process lasts 3-4 weeks;
@4th week email them, told me: the process lasts 4-6 weeks;
Then call DOS, told me: all the information @Shanghai;
@5th week tried fax them, failed, but got an email from them, told me: wirtting sooner could slower the process. Please feel free to contact the at July XX
@July XX emailed them, no feedback;
