Sorry to hear about the hard times. Being apart does not help either. This whole visa business is very stressful and requires a lot of paperwork, meaning you have to be organised and want things to work out. Best thing is to write down the sequence of things that need to be done, and don't push too hard on the timeframes if that is stressing him out. Once it is 'on paper' you can see the challenges and what needs to be done.

By the way, a new car doesn't have to be a NEW car. In the UK you can pick up a very good car for £3,000 which would be reliable and safe for long distance use. If he doesn't need to do long distances then £1,000 will get something safe and in reasonable condition.

Keep focused, you'll get there if it is meant to be!
