I'll try and make this brief.
Son (27) and g/f want to chuck jobs in and move to France in the summer. G/f is Australian, understands about visas, her visa runs out soon although she is able to get an extension here in the UK. She speaks French quite well. Does marketing. Believes she can find herself something similar in time.
My son has very, very basic French. Has been doing coding last 4 or 5 years. I don't understand coding. Does it require use of the language for the country you're in? If he can't speak French could he get a job working on software in France?
Just to say, this is only me pondering. I'm happy for them to go to France. Won't try and stop them, just wondering how IT skills translate in another country.
Merci buttercups!
