Since I’m not a personal university, I can’t offer any courses providing you with essential tips & information about visiting different countries as an American citizen. However, I have prepared brief 100-level posts in lieu of 100-level classes filled with information that was helpful in my travels as well as information I wish I would’ve known before going. These include entry requirements, exit requirements, and language/customs/laws (to name a few!).

DOM-101 (Dominican Republic)
ESP-101 (Spain)
FRA-101 (France)
GBR-101 (United Kingdom)
GRC-101 (Greece)
ITA-101 (Italy)
NLD-101 (Netherlands)
PRT-101 (Portugal)

If you are not going to one of the countries listed above, please look at my other posts regarding International Travel to answer more general questions.
