Hello Wonder,
Thanks for your prompt response,
To be honest, I would visit but you know the visa process takes some time because of this time taking I can not go, If I want to go for my training in August and I won't be able to make a visit. If I go for a visit I won't be able to go training.
I sent an email to Hillsbro flight training (Oregon) what you would say, I have been some good reviews especially someone who have been living there posted that it is good to go there.
Lastly, give me names according to your experience which you had. I can have a look and talk to them.
I look forward to hearing from you
