ATP

Does anyone know what is the requirement to write the US ATP? Canada requires 750 hrs flight time logged just to write it.

I assume you mean the FAA ATP written test.
You can take it at any time, no prior experience required.
The test result itself is valid for 24 months, so you will have two years to rack up 1500 hrs so you can take the practical test.

Cool. Would they accept Canadian CPL holders to write the exam?
