I have 3 month completed tcs I want to change my location my manager is ok but rmg is saying you should 2 year in base location.

RMG is making up their own rules. If your project has an odc at the new location, transfer is possible.

If your project does not have an odc, then you need to join some project with odc at new location.

As per transfer policy, minimum 2 years at any location before applying for transfer
