Be careful of Spain. I visited it and found it to be very hostile to foreigners. Now I can even say racist. Have a look at this BBC article. I dont think it just applies to a few bad apples.

If you like Spanish, as I do, teach in Latin America. Generally, they are more friendly and easier to get along with than the Spanish. Anyway, teaching English to Spanish students is fun because English and Spanish have many similarities and the language is very beautiful.
