I'm about to file I-90 to correct the wrong gender on my green card. But the INS instruction on where to send it is confusing. On I-90 form, it says for those who choose option D - INS administrative error: "To find the service center or NBC mailing address, refer to the USCIS letter that came with your form I-551 permannent resident card, also known as the "Green Card". The letter lists the address of the service center or NBC that processed your previously filed form I-485, I-751 or I-90 application. " In my case the address on the letter that came with my card is MSC at Lee's Summit, but I filed my 485 to Dallas District Office.
where do you think I should send my I-90 to? Dallas District Office or MSC at Lee's Summit?
Thanks!
