if you have the scan of you passport, it takes shorter, unless, it takes about 3 months. I had this experience 3 years ago, no idea if they've improved.
your time is limited, no idea when they can finish. they don't care if you have emergency.
thank you guys,
i called ind, they said i have to have a passport to get a return visa.
therefore, what only i can do now is to apply a new passport as soon as possible...
god & christ bless..
