JAA/CAA/CASA/ICAO conversion to FAA

[whoateallthepies]

My turn!

I hold a FAA fixed-wing PPL
I have a current ICAO ATPL(H)/IR and wish to fly multi-engine, two-pilot rotary for a job in the US. Can you help me gents? (and ladies!)

What's the minimum requirement to get working there? (Visa aside!)

I understand there will be a requirement for the computer based written test?

Can I pass a check ride on a light single-engine rotary for the license and then do the type rating later?

Would this all be added to my FAA PPL?

Thanks
