Hi all
I need advice. I have a type D student visa till december24th. I applied for a one year residence permit this week and I don’t have it. I have to go to UK. But the student visa is single entry. I am not a EU citizen. But last year I was in Italy and I enterred Spain on my Italian student visa and my Spanish visa is not stamped.
Now, If I go to UK, do they stamp my spanish visa on exit? and this means that I can not come back? Can I do anything in London to re enter Spain? Unfortunately, I didn’t notice the problem till today and my flight is tomorrow night. I have an important conference that I worked for it one year, and so I really have to attend it.

Anyone knows anything about this problem?
