Seeking recommendations for an immigration lawyer in Chennai with strong FRRO connections to help my friend check if he's banned from coming into India

I'm looking for an immigration lawyer who has good connections with the FRRO (Foreigners Regional Registration Office) for my friend's situation. My friend is worried that they might have been banned from entering India due to an overstay, and we need someone who can help us check the status and guide us through the process.

If you have any recommendations for lawyers with experience in this area or know anyone who has successfully handled similar cases, please share their contact details or your experiences. Your assistance would be greatly appreciated!
