Hi Jim, below is the scenario - I am a biotech major, with bachelors, working on H1B - I have my I-140 approved, in EB3 Category - Planning to do Masters in a totally different sector, in Information Technology. Questions: - Considering I get my EAD while I am doing my masters, can I transfer my existing EAD to new sector and transfer myself to EB2 category, once I have a master's degree in STEM area? - If I get EAD and go full time in my masters, will i be able to keep my EAD or it will dissolve? - Can I full time on F1 and later on come on my spouse's EAD? Please advise.
