I-485 (EAD, AP, FP)
Aliens who are physically present in the United States already are allowed to immigrate without leaving the United States to apply for an immigrant visa. This process is called Adjustment of Status (AOS). The USCIS will permit an application for AOS to be filed only if an immigrant visa is immediately available to the alien. Section 245(a) of the Immigration and Nationality Act (INA) governs the general AOS provisions.
Thanks Mr Rajiv Khanna for providing us guidance regarding travel on AP while being on H1-B. We are really looking forward to our India trip soon.
