Language degrees are hugely useful. Any business, trade, craft, skill, technical expertise can be learnt on the job, but language skills are hard to build in a hurry.

What else do you want to do once you have your language?

Many undergraduate non-language courses have options for placement abroad for people with a basic knowledge of the lingo so you may do part of your degree in the UK (or the US for all I know) and the other part in Spain, France, Germany, Italy or China. Language and culture - ideal.
