It’s not clear where you are based or where you intend to use your FI rating.
If you are in the UK and intend to seek out one of the few FI jobs on offer here at the moment, I strongly suggest that you train here.
Most clubs and FTO’s are now very choosy, …‘cos they can be. Most that I know will offer jobs in the following order
1 an FI trained by themselves
2 an FI trained locally
3 an FI with loads of UK hours
9 a 'foreign' trained FI
No doubt, there are excellent approved schools abroad, but don’t put hurdles in your way, there are enough there as it is.
Good luck
