Here is what it says about Passport Cards.
The U.S. Passport Card can be used to enter the United States from Canada, Mexico, the Caribbean, and Bermuda at land border crossings or sea ports-of-entry and is more convenient and less expensive than a passport book. The passport card cannot be used for international travel by air.
Since you will be getting there by air, you WILL need your Tourist Passport, plus a Student Visa since you will be attending school.
I suggest to write down ALL questions and bring the list with you when you go and talk to the people.
