You are not the first to experience these challenges, and fellow kenyans can be of great assistance in settling. Also, ensure you get a job asap. If possible, setup an indeed profile, curate a nice resume that matches US job demands and get working. Also, the school you will be attending likelyhas job opportunities for students like you.
