I am a dual citizen of the United States and Dominican Republic, at this moment I am in Dominican Republic spending some time wiht my family. I’m planning a trip to Spain for about a month or so to see Spain and might be visit some family and friends who live there.
My questions are the following:

How much cash in Euros do I need to bring for a month, and if it’s true that immigracion/custom in Spain will ask me to show sufient funds for my stay in Spain?????

Will they give me a hard time at the airport (custom/immigracion) when they see that I am a dual citizen of the United States.??? (I am traveling with my US passport)

Can I travel with a one ticket only or do I have to buy a two way ticket?????

Any help will be appreciated it.

hi Tallman 1818,
you seem a bit fool of you if you care about your double nationality. Just what do must do is show your american nationality, nothing more! If you come as a tourist you must show return flight and an equivalent 60-90 euros per day for your stay.If you plan to visit (and justify so less money spending requirements) some familiar you need 1500 euros for 1 month stay more or less.You only have to use commom sense.Police want to see if you are a real tourist and you entry legally.
What will happen if I visit USA without hotel reservations, without return flight and with only 300 dollars in my pocket?
good luck!
