I did the flashcards, too....and the test was as easy as can be- really! If you do those for 10 minutes a day, you'll be fine! Good luck!😃you're almost done👍😃
Bring him, just in case- if you have a pending I-751 , it might be a combo interview. That was the case with me. All the best for the interview- and don't worry, it is a piece of cake😉👍
He might just request your I-751 application and papers to actually look at it & then approve. Should be fast and straightforward. Only thing left is for you to take the oath!😃Congratulations 👏 🥳🥳🥳
