Facts from one of our clients
I have applied for 485 as the primary applicant and my wife is the secondary applicant. Right now both of us are on H1 visa. We had applied for EAD and AP and intend to apply for renewal soon as we near 120 days.
I am on my 7th year of H1 and my wife is on 2nd year of H1 and 3 year of (H1 and H4 combine). Her current H1 expires on April 2010.
