Student pilot having to change schools
Let me think? (not to hard to) you have been to a US sausage factory, made to fly twice as much as you would have had to in the UK, spent twice as much as a PPL would have cost you in the UK (about $12,000) and you are still waiting for a check ride?
And when you come back to the UK, you will have to be taught how to navigate and the correct procedure for carrying out stalls!!
You would have been better to look at the schools in the UK, (and there are plenty of them) who could have got you done in 40-50 hours, skills test as well and had some money left over afterwards.
You need to sit down and work out on two pieces of paper, the pro's and con's for training in the UK and the USA. While there are some very good schools that teach FAA in the USA, there are not many good schools that can teach EASA PPL properly and in accordance with rules, regulations and most importantly in accordance with an EASA PPL syllabus.
Whatever option you choose, think wisely before you spend any more money, and good luck to you and your career.
