The only way to file for green card without even a Bachelor's degree is possible in one of three ways. 1) marriage (does your boss mean to do this?) 2) special skills labor (for this you need to be working for a job that needs special skills; most people who file under it work as chefs and the like under EB 3. Like someone said above, it takes years. One guy got it in a little more than 4 years. The employer also has to go through a lengthy process to prove that there is nobody else among citizens and g-c holders to take that job! Most difficult. 3) You are an unmarried and under-age child of a US citizen or green card holder! If you are not in in any one of the above situations, either your boss is kidding or is simply dumb about the green card process. If he/she means to screw you, that's another thing. As noted above by someone, once you file for green card and are denied, there is no way you can stay on student/F-1 visa because you then violate the non-immigrant purpose of F-1. If anyone is ever going to go for a g-c, first get H1 B, the dual intent visa and you can take any route after that without risking your status, unless you are of extra ordinary ability (researcher/professor/scientiest, etc.) to qualify for EB 1 in which case you get the g-c as easily as the rest get a driving license. Almost. My free advice. Good luck and take care.
