They need 4 yrs exp. for ABET degree and 6 yrs for NonABET. Our degree from Nepal is considered non ABET, they dont care even if you have an ABET masters. If you have 6 yrs experience then you are almost there. 2 yrs experience from Nepal is not equivalent to 2 yrs of US experience. Wherever you work you need to show design experience, any field experience or teaching doesnt count much.

You will have to submit your transcripts directly from TU and its verification/evaluation by NYS will take a while. So its always good to start your application process before completing the required experience. If you start your application after completing the required experience you will loose at least a year by the time your application is complete.
 
Good Luck.
