Hi guys!
Just to give an update. I received my visa on 1st October & am now in Germany. Sorry about the late update. There were some hiccups, but its all sorted now. Here's the gist of my process:
Mid-August: Employer files for pre-approval (Vorabzustimmung) at Munich Alien's office.
4 Sept: Visa Application submitted at Mumbai Consulate
14 Sept: Visa-pre-approval (Vorabzustimmung) faxed from Munich Alien's office to Mumbai Consulate.
17 Sept: Mumbai Consulate denies receiving the fax.
18 Sept: Munich Alien's office faxes the Vorabzustimmung to Mumbai Consulate again
20 Sept: Mumbai Consulate again says they haven't received it.
26 Sept: I call Consulate to find status and they say they still haven't received it. They call back 30 mins later saying they have received the approval (I guess the FAX took 8 days to reach Mumbai). Ask me to submit passport and that I will receive it back on same day.
27 Sept: Passport submitted for stamping. Not returned on same day (no reason given)
28 Sept: Passport still not returned
1 Oct: Passport still not returned
2 Oct: Passport received
3 Oct: Arrived in Germany
5 Oct: Got residence registration done. Officially a Münchener now!
4 Feb: Appointment for electronic work/residence permit (and yes, its February)
My visa was issued within a month of application just because of the Vorabzustimmung which is a pre-approval from the Alien's Office. This can only be done by your employer. Otherwise be prepared to wait for at least 6 weeks, because I think the Mumbai Consulate people just send the application to Germany and file them by date and only open them when 6 weeks are up.
Another piece of advice: some of the phone ladies at the Mumbai consulate are the rudest you can find, so dont be disheartened if they just hang up on you. The first time I called to ask about whether they received the fax, she didn't let me say anything and just asked my application date. When I told her it was two weeks ago, her exact words were "Why can't you be patient? Don't call before 6 weeks" and she hung up. But I kept calling since I knew they should have got the approval and they kept denying it. Finally, they found the fax on 26 September (which was sent on 14th/18th) and if I hadn't called, they would have waited for the 6 weeks before opening my file.Â
Also, I have no clue why they took four w
orking days to stamp my passport (4 working days plus a weekend = total 6 days).  And like an idiot, i had booked flights for 30th and hotel in Munich (given Oktoberfest, I had to book hotel asap). So had to reschedule flight & change hotel bookings and pacify an annoyed boss who was expecting me at work on 1st Oct. But I got my visa in a month, so I guess I should be happy about that!
