DS1, 15 (December baby) took part in an exchange programme organised by his school last year, to Madrid. He & his exchange partner got on very well with each other & with the respective families & message every day still.
They would like to visit each other again, staying with families. Both sets of parents are happy to do this. Is this possible? What would we need to do? Would he be subject to the recent money rule? He is British with current valid British passport only.
I will also email the Spanish Consulate (I think?), but just wondered if anybody had any idea about this.
