This. The dude has no idea what they are talking about. It's amazing even on HN people are openly giving their opinions while being completely uninformed of the facts. Imagine the discussions elsewhere.
I’m informed on this topic… Can you correct the mistake? If I show up in China (or the USA) on a tourist visa with the plans to pursue a marriage and permanent residency, does that mean I get to backdate my permanent residency to the tourist visa because I’m able to pursue a marriage (PR)?
Can a nonimmigrant in H-1B or L-1 status intend to immigrate permanently to the U.S.?
Nonimmigrants in H-1B or L-1 status can be the beneficiary of an immigrant visa petition, apply for adjustment of status, or take other steps toward Lawful Permanent Resident status without affecting their status. This is known as "dual intent" and has been recognized in immigration law since passage of the Immigration Act of 1990. During the time that the application for LPR status is pending, a nonimmigrant in valid H-1B or L-1 status may travel on his or her visa rather than obtaining advance parole or requesting other advance permission from USCIS to return to the U.S.
