Q1. Can a legal permanent resident(LPR) change career after say one year from his AOS approval to an entirely different field from the one for which his labor and his AOS was approved? Will this raise any red flags at the time of citizenship? Q2. In other words, after receiving green card on the basis of say job in computer industry, when can one change his/her profession to an entirely different field (let say opening up a restaurant or go into real estate on full time basis) without jeopardizing the citizenship? Would waiting for one year(or some other amount of time?) after AOS approval be good enough to satisfy the "intent to work for in the field noted in labor application on a permanent basis"? Q3. Is the person after receiving green card on the basis of employment in certain field stuck in that field for ever? Q4. What are you thoughts in general about this scenario and how should one go about it?
A1. I see no problem with this nor do I see any red flags.
A2. Sure. Why not. Permanent does not mean forever.
A3. Not at all.
A4. Nothing else I can think of.
