There is potential for employment in Gibraltar. I understand that the rent for property is very high and wages lower than in England. One suggestion is to work in Gibraltar and live over the border in Spain. What's it like getting over the border and back again each day. What are the nicest areas away from Lalinea to live in?

Please bear in mind that there will be arguments between the UK and Spain over Gibralter during the transition period, and border crossings may well be in the firing line. This has been less of a contentious issue when the UK was in the EU, but as it is now leaving this WILL change due to the loss of FOM, but, as yet, no details have been worked out.

Can you drive a UK registered car in Gibraltar?

It’s fine and probably will continue to be. All of the big businesses have prepared for border issues.

You seem light on research! I would recommend searching for answers online and making a few visits to the general area before moving.
