My Thai girlfriend has a six month visa to visit the Uk and we would like to go on holiday to Spain for two weeks while she is here.Is this possible without too much expense and documentation required for visas etc.
The Embassy of Spain in London may not entertain a visa application as it requires it be done where she legally resides. You can try and, in advance, complete the application. While the expense is modest, it takes some effort to assemble the documentation: passport and previous visas, travel insurance, purpose of visit, flight and hotel reservations, and proof of means of subsistence. Before you do, you might enquire about the feasibility of applying through the consulate.
