1. Student should be easy to get a credit card. Because they usually can get a better job after graduation (compared to those who didn't go to the university). You can fill out an application form (available in most banks), mail it or talk to some one in a bank.
2. You can get additional card for your spouse for free. In this case, he/she sign the bill, you pay the money. :) The only differenct is your spouse won't get good credit history. He/she will have some problems if you are seperated in the future.
Hope this helps
