I completed my project1 with ABC client and XYZ vendor through Indian consultancy 1 year back. That was my 1st project in US. I came US in 2014. I am no more associated with Indian consultancy.

Now, I want to work directly with same XYZ vendor with same ABC client for project2. (They have opening for project2 and they are interested on me). I know i need to put same resume there.(With all 7 years exp.....lol)
But if the vendor wants to go for background check, will I be in problem?

Please share your knowledge.
