Landing and AVR Experience

Hi All,

First of all thanks to everyone who helped me for successful landing process.
USA - Canada: I entered thru Detroit - Windsor tunnel ( at Michigan), I landed at 12.30 pm Immigration people are nice, they asked me all the paper work- Its fine, Then I went to Canada service office which is right behind the Immigration office, I applied SIN ( its just 10 mins process) i got my SInumber they will post the SIN card in a week. From there I went to RBC( Royal Bank of Canada) which is 2 mins away from canada service office, I opened and account ( its 30 mins process).

Canada- USA: I drove back on the same day ,I am onH1b but no Stamp in my Passport, I had a plan to use AVR process. US Border service people asked me my passports ( I have F1 visa its valid till 12/2009) he asked me wht are you doing in usa and For which company you are working for .... like that. He didnt check my H1B document or H1b- I94 document, simply he scnaed my F1visa page and told me that you are all set and good to go.

This is my Experience, Guys i have a question Does he ( US officer) required to stamp in my passport? He didn't processed my H1b-I94 document.

Thanks
Sri
