[kikki]

Hi,
I have been working for a company under my H1-B for the last 4 years.I joined the company while I was a F1 student. The company is located on the campus.Is an outside contractor that provides services to college students. I joined the comapny as a student worker, working 20 /week as authorized for international students. In my 3 rd year in college I did an approved CO-OP fulltime(INTERNSHIP ) with the company .I continued working there parttime(authorized on campus employment) until I graduated. After I graduated I was offered a job as manager.I applied for my H1 B and was approved. The question that I have is can I apply for employment based immigration?(greencard).Is it a problem that I joined before i graduated? The job that I currently do is vastly different from the job I first did when I joined.Please advise me how I can get my greencard. Thanks for your help!!

No problems. Can file for GC anytime after getting H1 B. There's a possibility that H1B and GC positions would be different, as in your case. No problems in that as well
