You do have a Last Name field in Indian passport. You are merely confused. Last Name means Family Name or Surname.Indian passport has two rows for names:SurnameGiven NamesSurname has precedence over Given Names. Henceforth, you will notice that Surname field appears above Given Names in passports. This is the norm followed by other countries as well.I don't know if you have middle name or not. I am going to consider two options here: one with middle name and one without middle name.Option 1: With Middle NameFor the sake of understanding, let me assume that Ramesh is your middle name. Full Name: Abhijith Ramesh NambiarSurname: NambiarGiven Names: Abhijith RameshFirst Name: AbhijithMiddle Name: RameshOption 2: Without Middle NameFull Name: Abhijith NambiarSurname: NambiarGiven Names: AbhijithFirst Name: AbhijithMiddle Name: [None]
