Hi Kalyan,
I have submitted marriage documents, letter requesting visa, job contract, permit and passport copies, apartment contract copy in the "Gemeinde" (city office where i registered my new rented appartment) here in Switzerland. The City office (Gemeinde) said that after 4-6 weeks i will recieve an authorisation letter for visa for my wife and they will send it to me by post to my address in Switzerland and at the same time to Switzerland consulate in Mumbai. And then my wife can go to Swiss Embassy in India and submit application form and can collect visa.

Now please clarify me, as u mentioned earlier, it takes 3 weeks after submitting all the mentione above documents in Swiss Consulate in India as u r wife did. Is the same process to all who are working here on B permit?
1. When should my wife visit consulate in India? i mean after getting authorisation from Migrationsamt ?
2.and marriage certificate must be attested with home ministry while applying for visa or by any authorised lawer will work?
Hope i am not confusing u and sorry to bother.
Regards
I am from Andhra Pradesh.
