Dear Aspirant, previously there was no bond allowed for All India Quota students in medical filed but now bonds are uniform. Bond varies from college to college. But some changes have been made by MCI about the bonds.

According to the news in The Hindu-

The bond period for MBBS candidates should not exceed one year, and the bond value should not over 10 lakh for those admitted under AIQ. The bond value alone could be increased to a maximum of 15 lakh for students admitted under state quota. After a year of bond service, the candidates could be allowed to serve for one more year. I hope you are clear now. If you have any other queries feel free to ask. All The Best!!!
