The final process before I leave is getting a Visa. If you don't know, a Visa is essentially permission to enter another country. Without a Visa your passport is worthless, if you're planning an extended stay. For instance, South Korea requires a Visa if you plan on staying more than 90 days.
I went to apply for mine yesterday at the Korean Consulate here in L.A. (Wilshire and Vermont) , they made the process very effortless. There was no line and I was in and out in less than 5 minutes.
From the information I was given I anticipated a grueling process that took several weeks to complete. I came in with bank statements, financial aid awards, a birth certificate, THE WORKS; I didn't want to have to go home and come back for any reason. I filled out the application and took all my materials to window 2. The woman behind the glass only took one passport photo, my passport, the application, and Yonsei's certificate of admission. It cost 45USD and I can pick it up today at 11 a.m.
