UK citizen training in the USA

[awair]

You didn't mention your age, or status, as this could drastically affect the 'best' course of action.

Do not discount the US option. There are numerous options there, that are unavailable world-wide.

A couple of current considerations:

1. At the moment there are less instructor opportunities, due to furlough, and the typical career route in US.
2. Immigration is restricted, due to C-19 unemployment.
3. The hours you are 'guaranteed' as an instructor, do not always materialise.
4. However, you will have fun, and the weather is better.
5. Marry an American... stranger things have happened!
6. After training, consider an alternative visa?

There is no 're-doing' of flight tests. As a professional pilot, you will always be constantly tested. It’s a skill that you have to maintain, so if you go FAA>EASA, there will be additional training and testing, but you are 'buying' two products, probably for no more than just doing the EASA-only route.

Biggest tip, if I had to do it again: don't forget the 'fun' part!
