What r the advantages and disadvantages of this?
I don't see the disadvantages but it has more advantage for you to add your wife now than starting the process after approval. If they transfer it to local BCIS then it might add three or four months on your application to get approved if you wait and start a process after you got approved it will take years for your wife to get her GC (3-4 years). Even it is taking more than 2 years for Citizens to sponsor a spouse.
This is just my opinion it might be wrong. Act accordingly
