H1 extension and ssn wrontly printed

1. You can submit all paystubs you have. But based on your earning for the previous year on your W2, they may send you a RFE.

2. Contact IRS and ask employer to fix it.

My h1 visa is getting expired this september, How long before I have to
file for an extension ? What are the documents that are needed for that ?
A couple of paystubs is enough or I have to submit all the paystubs that
I got during my h1b period ?

The problem is, I have arrived at US last april, working since september 08.
so i cant submit paystubs earlier than that ..meaning I cant submit the
paystubs when I was in bench

2) in my w2 form, and paystubs so far, the 1st digit of my last 4 ssn digit is printed wrong, my employer is working on that, but i want to know will this
be an issue for my h1 extension ?

I appreciate if any senior members adivce me

thanks
