Can I transfer my L 1B visa to a green card? How to turn?

American L 1B visa can't apply for a green card through EB 1c, but only through PERM, that is, apply for a work permit from the US Department of labor (labor

Certification), and then submit a green card application to the Immigration Bureau after approval.

Because this kind (EB2 or EB3) has a schedule, the perm processing time is not short, so it is time-consuming. In addition, the longest time limit of L 1B is 5 years. If you can't catch up with the schedule within the time limit of L 1B, you can apply for changing to the status of H1B.

The holder of 1)l 1b was an executive of a China company for one of the three years before he entered the United States with this visa.

2) American companies have been adjusted to executive positions or promised to change to executive positions after obtaining green cards, so holders of L 1B can directly apply for EB 1c green cards without applying for L 1A first.
