I migrated to the United States at the age of five with a passport. The easiest thing to overcome was the language barrier. I picked up the English language pretty quickly.
The hardest thing has been this year. I turned 18 and unlike my friends, I can't get a driver's license.
I also can't get much financial aid through the government for college due to my status. What I do find exciting about the U.S. is all the opportunity one gets.
