Quoting
Mr. Knowitall
With that history I expect you will face skepticism upon any future entry that you in fact intend to return to your nation of origin as promised. The issue would seem to be less, "Should I apply for a B1/B2 visa or a J1 visa" and more, "How will I reassure the State Department and USCIS that I have very strong ties to my nation of origin and won't stay even one second longer than I'm authorized to remain in the United States?"
From what you write, it sounds like you're hoping to immigrate to the U.S. - which is the opposite of what you want the U.S. government and immigration officer at the port of entry to infer.
