UK trained Physio relocation to New York

Hello!
I'm a UK Physio with 4 years of practice looking to relocate to New York city. I was wondering if anyone knew what the requirements are to be able to practice in NYC? Not sure if its possible without a masters, or what the job situation is like out there? Any help or direction would be gratefully received. I've been on the FCCPT website and the op. nysed site with no joy. If anyone knows of any UK based locum agencies that facilitate moves to NYC as well, that would be great.
Thankyou in advance :)
