I have 2 visas B1 and H1B. Earlier I traveled on B1 in June 2010 . After that I got H1B visa on Aug 2011 and since then I have not travelled to USA.
I am travelling to USA again in next week ( Feb 2013) on H1B and my H1B visa is valid till sept 2013. My company will apply for my H1B extension in March 2013 ( 6 months prior to visa expiry ).
My questions are :-
How many days or months I can stay in USA after my H1B expiry ?
Suppose I get I-94 for one more year means till feb 2014 and extension is for 1 year means till Sept 2014 , when I should come for stamping of H1B extension in India ?
Suppose I get extension for 1 year means till sep 2014 and I-94 for 2 years means till feb 2015 , when I should come for stamping of H1B extension in India ?
At what types questions I can expect on port of entry ?
