Can I get an FAA restricted ATP certificate with 1000 hours total time? I have an FAA Commercial Single-Engine certificate with 260 hours total time and a Bachelor's degree in Electrical Engineering issued in Indonesia. I have an Indonesian Passport and I'm working as a copilot flying DHC-6 Twin Otters in Indonesia. I'm planning to get a restricted ATP certificate in the USA but there's a question.

Is it possible to go and get a restricted ATP in the USA after flying 1000 hours TT on DHC 6 Twin Otter in Indonesia?
Unless you were trained through a military flight school, the answer is no.  Part 61 states that you need a minimum 1500 hors TT to apply for an ATPL unless you either attended a military flight training program or an aviation degree from an accredited institution.
