Trackitt has some useful information and I am sharing the link below.Also buried many posts deep in this thread is also some useful information.Anywaz for the benefit of all will put the AVR checklist below.Some points have been overlooked in this forum and have not been posted.http://mail.trackitt.com/usa-discussion-forums/i485-eb/678557493/canada-automatic-revalidation-process
1.Expired Non Immigration stamp in your passport ( Can be F1, J1 ,H1 etc )
2.Expired I-94 card.Please do not surrender while leaving the Usa
3.I-797 H1B approval or your new visa approval receipt along with the new I-94 attached to the I-797.
4.You have not travelled to canada within 30days or entering Usa within 30 days of using AVR.
5.You are not from Iran, Syria, Iraq, or Cuba.
6.Also nationals of certain countries have to do what is called an exit registration ( NSEER) .Please google.
7.Also you must not have scheduled an visa appointment http://www.immigration.com/visa/general-nonimmigrant-visa/national-security-entry-exit-registration-system-nseers
Backup plan to deal with US Immigration officers who do not know the rule or intrepret it differently.
1.Please carry all the documentation required for an visa stamping if the need arises.Also this documentation can be used to prove you are an legal non immigrant to USA and are only visiting canada. Employment papers, Tax receipts,W2,Employment letter etc.
2.Please use the canada entry stamp to show the stay has been less than 30 days.
3.Carry an printout of the AVR memo.
4.Also carry additional articles from the USCIS site.
5.Be prepared to schedule an visa appointment at calgary or Toronto if things dont work out.
For some people AVR was very smooth.For others like many who posted on trackitt when they travel from smaller airports it can be quite tiresome and be prepared to patiently explain the case and sort out the whole thing.
I am doing my landing on 31st Aug. Since my US visa expired in june, I will be using AVR while re-entering US. The visa issued by Canadian embasssy is "immigrant" visa. Can someone clarify the following :
I am not sure how I will be able to convince the officer that I am a visitor when my passport has a canadian "Immigrant" visa
"1.Please carry all the documentation required for an visa stamping if the need arises.Also this documentation can be used to prove you are an legal non immigrant to USA and are only visiting canada.

Thanks in Advance
