thyangboche, you need to ask the lawyer, and if he can show that this is can be filed under EB2. I did the same job, and the minimum pay was much higher because of the minimum requirement of Masters Degree. The process can take any where between 6-18 months, usually most being completed within 11 months. I think it takes more time to get things ready for PERM rather than the process. Some of my friend's had to wait longer for PERM and I 140 approval, but others were much faster. Best of luck for your GC process.
