Wanted to know if law firms in india allow you to intern in one city and upon getting a ppo allow you to join the office in a different city

Please do let me know!

Not sure about others, but CAM did let the '23 batch do this. It is a different bit that the overwhelming number of people who filed for Noida office didn't get their preference and were allocated elsewhere (Noida's is a smaller office).

Right, so it is technically possible to intern at one office and be allocated to another ?

Cam will decide on the "influence" factor of candidate.A judges daughter will get city if her choice whereas a Harvard LLM pass out will not get city of preference.
