[gaelle]

Hello, I am Gael a spanish student taking classes in The States. I was an au
pair for two years in Usa, I applied in the states for a student's visa and
I got my F-1 like 6 months ago. My question is the next: I would like to
visit my country in Christmas Holidays, but I am afraid If I could have
problems to re enter to the States. Would I need to get another visa In
Spain....? Or what should I do?

Thanks so much!
best,

Gael
