I am doing the Organic Chemistry Phd study with F1 visa in U.S.A. but I am a PR of Canada, the trouble is I have to study in U.S.A around 4 to 5 years, I am afraid that if I donot go back to Canadan during these year, my PR status will expire. I do not know if anyone of you have a good suggestion for me to keep my PR status and at the same time I can finish my study in U.S.A? If I keep study in U.S.A I donot know if it is easy to find a job in the future in U.S.A. I really do not know what I can do now.
Plz help me!
Thank you so much!
