My children and I live in the US. I have a Spanish boyfriend/not father of children. We will be coming to Spain this summer to get married and live there. What is the protocol? Do I get married in the first 90 days of my tourist visa in Spain? After we are married do I have to return to the states to finish paperwork/ apply for residency or can I stay in Spain and residency is granted to me and my children right away once I marry? I need to get my children their NIE numbers so I can enroll them in school in September. How long before September do you recommend we get married so we have the numbers in time for enrollment.
