Dear Ms. Clark,
Thank you for posting your request on History Hub!
Neither the National Archives nor Ancestry will have the information you seek. We suggest that you file a FOIA with the US Citizenship and Immigration Services (USCIS). See Request Records through the Freedom of Information Act or Privacy Act for instructions. You also may wish to request an appointment at the USCIS field site nearest to you. Please see myUSCIS - Schedule an Appointment. For more information about green cards, see Green Card and Green Card Eligibility Categories. Finally, you may wish to consult with an immigration lawyer for any legal advice.
We hope this is helpful.
