LC and I-140 approved. I-485 has been pending over 180 days. I would like to switch my line of business, but i am not sure if new position will fall in to the category under which my LC was approved. i am currently a tax accountant and would like to switch to financial analyst.
could anyone please help with determing whether AC21 will apply if i change my position?
thanks a lot in advance.
