Now my question is there is a big Gap (2 years---2006,2007).Will USCIS check these ??? And ask about these?

Over all of genuine 4 years of IT exp ....

I do not want to put any junk exp ...Kindly suggest .I have travelled from Canada to USA 7 times on B1/B2 visa .

This is my first H1B Visa application to USA . 10 years back my dream was to study in USA but came to canada and finally got PR here.
Please advice how to manage the GAP 1 mentioned.
