My understanding is that as American citizens they do not require a Residence Visa to Reunite a Family Member with a Citizen of Spain or Other EU Country in order to enter Spain.
I am taking this information from the Visa information and Requirements page of the Consulate of Spain in Washington website (http://www.exteriores.gob.es/Consulados ... Visas.aspx).
They are planning to arrive in Spain on July 1 but I will not be arriving until July 15.American citizens and those of nationalities that do not require visa according to the above-mentioned list (Anejo 1 ICC) do not require a residence visa and must apply for their residence card once they arrive in Spain. They will need to have the marriage properly registered.
If this information is correct, my question is, will they be able to enter Spain before me? I will provide them with copies of our marriage certificate, my passport, employment letter, and flight booking.
Thanks for any help you can provide.
