@mech: I got my passport back in about 2 and half months...I hope that you do not have to send "chiya kharcha" and wait at the most for a month and then inquire if you dont get until then.

@keyser soze: I am positive about the photographs size since I sent the same sized photographs. About sending the original citizenship certificate, it is not mandatory but they recommend you to do so. If you do not send the original one, they told me that they have to send the photocopy for authorization and that would lengthen the process and you might have to wait longer to get your passport back. If I were you, I would send the original one.

Have fun!!!
