Thanks for your question.
Please could you tell me your nationality?
When you say "we" do you mean your spouse?
I look forward to your response.
Thank you for your question.
I can confirm that as an Afghan national, your son in law will need a visa to travel to Spain.
I am afraid there are only two Spanish consulates in the UK either London or Edinburgh.
Since his wife is British, he should be able to obtain a visa as a family member of an EU citizen, which means the visa should be free of charge.
Visa applications to the Spanish consulate have now been contracted out to VFS Global. You son-in-law must therefore apply on-line:http://es.vfsglobal.co.uk/
In the event that your son-in-law cannot obtain a visa in time (since it usually takes at least 2 weeks to process), he should contact Your Europe Advice as will be able to assist him further:http://ec.europa.eu/citizensrights/front_end/index_en.htm
I hope this answers your question.
I hope that my answer was useful to you.
Please let me know if you require anything else.
If so I'd be grateful if you could accept my answer so that I may be compensated for my time.
I thank you in advance.
