ETOPS773,
If you are going to fly on a Student Solo Certificate, you will need to have either an F-1, M-1 or J-1 Visa. It is a "Student" Certificate.
Also, you will need to be signed off by an instructor for each cross country flight and you will not be able to take passengers.
In addition you will need to review all maneuvers with the instructor and do a minimum of 3 hours of cross country time with the instructor.
It is better to just get the full FAA PPL and have an unrestricted licence that allows you to take passengers, fly at night and it complies 100% with the rules.
Take Care,
