Arrey dude.. i went to the Bbay RLO but the concerned people out there are so rude and unhelpful..
i went with all my documents and he is like " FAA cpl pe kaha likha hain kee tumhara english proficiency ka level kya hai, humko likhela chahiye.. nahi toh exam do"..
but now as you say that Delhi RLO can do it then i will try my luck there..
