The DS-260 is the main ‘Alien Registration’ form that requires lots of details and information about the intending immigrant. It’s long BUT it can be saved as you go along. It took me 2 hours 30 to complete it…and I had most of the information on hand ready! Unlike all the other forms in the process, it’s submitted online, so it’s difficult to find copies of the form online to prepare yourself (the others are mainly downloadable PDF files that can be filed in the computer and printed or filled in with pen). Here’s a guide to what the DS-260 form includes.
