Hi,
My sister who is a US citizen filed a green card request for me many years ago. About 4 years ago I was set to go to the embassy to have my interview, however because of financial problems I wasn't able to make it there. Unfortunately, I didn't send them a letter or anything to explain a reason for not showing up. Now after 4 years, I want to go to the embassy or at least continue the process. Could you please tell me if I can continue the process or I have to start over again. By the way, 2 of my other sisters whom my US citizen sister requested for them also went to their interviews 4 years ago and got their green card.
Thank you for your help.
