Spain belong to the Visa Waiver program. I already bought the ticket to go see my honey in December. Do you think Immigration will let me in? How can I convince them that I´m coming just for a few days, that I will leave by January? Any advice? Thanks.
You should be fine. Just make sure you bring ties to Spain, like a lease and a letter from your employer stating when you're expected to return. My fiance had no problems visiting.
