Thanks to everyone who take time to answer the questions. You are really doing a noble job.
I am on H1 with I-140 approved. Waiting for PD to be current. I am planning to take study leave from my present employer and go to college Full Time to do Masters.
Will I loose my I-140 and the chances of GC?
What are the best options?
Can I take F1 and continue to be employed to finish my GC?
