For those thinking about switching ....
My 2 cents for those who are thinking about switching from 485 to CP there is a lot of risk especially if ur. job is not safe :
1) The petition that you make to swicth from 485 to CP takes about 8 months to a year. Yes you may do Attorney certified CP once 140 is approved but still it will take 4-6 months easy.
2) The 140 with CP has no portability so if u lose job, you have to start GC from scratch.
3) Cannot use EAD and AP.
4) If there is a problem in CP interview, there is no recourse like appeal or MTR etc.
5) What if you swtich and soon we get a memo allowing portability of 140 after 6 months filing as we have in 485 too. I know there is a strong rumor floating on this one.
In my view people who switch are extremely confident of their job situation for coming year or 2.
So think about it all, discuss it with your lawyer and friends and make a informed decision.
