for the visa process it will take one day only, "if" they submit all the requirement and dues to the emigration for transferring. and after that, if you got the blue visa you will go to medical, medical take three working day before you get the result, then CID for finger print after you done all this thing you're passport along with the blue visa should bring to emigration for the sticker (Its mean visa issued to you) finish..... :)

Good luck......
