Can an Approved I-130 beneficiary outside the USA enter with a non-immigrant visa, then proceed to file for a greencard (file a form I-485) or must it be an immigrant visa?
Background
I am a US citizen and my mom's I-130 was approved in 2022, but she is not in the US. The instructions are to file form I-824 to have her approval copied to the appropriate consulate to process her immigrant visa. That will cost $465 if I file before April 1 (seeing that fees will increase from that date). Then the consulate fowrad to us the next instructions.
Because it is easier with myself handling it in the US, Is it possible for her to come on a non-immigrant visa and then file form I-485? The plan is to inform the US embassy abroad that we prefer continuing the process while she is the US.
