EB1A I-485 Immigrant visa processing

Dear Anil ji,

I am going to file EB1A I-140 in few days, I have chosen Immigrant Visa Processing. As now EB1A filing date is almost current, should I choose, “I will file I-485 from USA in I-140 form”?

Second I have EB2-NIW approval with May 2019 date, how hard it is to move prority dates from one category to another category?

Thank you so much for your help!

Best Regards,

If you are in the USA and your dates are close enough, you should choose to file i485 within USA.
