No, according to present scenario, if you do your pg in the US or UK after completing MBBS from Russia or any European country, there are low chances that you will be exempted from writing the FMGE. In order to practice as a doctor in India one needs to clear the FMGE exam but there is an exception for 5 countries which are:
1) USA
2)UK
3) New Zealand
4) Australia
5) Canada
If a student does both UG and PG from these countries then they might be exempted from writing the FMGE. So, only doing pg will not be very helpful.
