Applying for OCI (Overseas Citizen of India), they require some past travel & residence date details (very bureaucratic) at Indian Consulate. I don't remember this info but it is on my N-400. Where do they store old, adjudicated N-400 application forms : in my A-file at the Regional Service Center (or NBC Missouri) or the US District Court or scanned it in INS database ?
Is it easy for USCIS to retrive ? What is the best way to get it ? Would it take long ?
