Thanks All,
All you comments have been helpful.

@jonny, Thanks much for the information, it’s very helpful. Now, I  feel that I really want to move there.

 

@peacefulsoul,  When I  made up  my mind to move and told them abt it, the company wants to file on EB2, but I think it's more wiser to take what to have in your hand than to wait for which you aren't certain abt.
