Okay apply for TPS/EAD once approved for Nepal (likely to be in next week or two). Once TPS is approved you can stop going to CPT college but only can start working once EAD is approved ~90 days of application, so you may wanna keep going to CPT college till EAD is approved. Once EAD is approved ask your boss to file form GC (we all know how H1B 2017 gonna turn out again). GC is a long process, just in my case they started in late February and i am still on PERM phase so 18 month of TPS would be barely suffice if you start working on it. Another good news is any nation granted TPS has never been revoked it TPS after month. Atleast they get renewal for 4-5 years. Good luck
