How to change work location from one city to another city/state? Do we have to raise requests in the system or supervisor can do it early

Yes you need to raise a self initiated transfer but before that you should be having a min of 2 years of experience in terms of stay at work location or else a genuine medical reason by your guardian or marriage plans...It will be approved by supervisor along with base plus travel RMG when in project or else only by both base and travel RMG if you are on bench Path for the same: Ultimatix>Gess>Travel>Self initiated transfer request

You can raise a self initiated transfer from GESS > Travel Request
