I am a Polish student in my second year of college studying and living in Frankfurt, Germany. I applied twice for a visa to visit the USA when I was in high school in Warsaw and was denied, partially because I went back after one month after getting denied the first time.
I want to go to see the USA and visit my close friend there for about three weeks.
Should I apply for a tourist visa while in Germany or would my chances be better if I spend the extra traveling money to go to Warsaw to apply?
