a bit of background information: my passport does not allow me visa free access to europe nor Schengen so I would need a Visa.
I will be going for around 6 months of exchange in Switzerland - which means a visa 'D'. However, I have no intention of going early so I may go in late February.
The thing is, in (early) January, I am intending to travel to UK and France/Netherlands with some other friends. Obviously I would need a UK Visa. However, regarding the France, would I (or more specifically, Can i ) apply for a Schengen Visa ? Because the validity would overlap into the start of the Swiss Visa 'D'.
-> Because aside from that, I guess the other way is to request for the Swiss Visa 'D' to start earlier (i.e. to start on the day i intend to travel to France).
I'll be requesting a multiple entry visa of course because after the UK/France travel, I will come back to Singapore (i'm not a Singapore passport holder) to stay for another 3 - 4 weeks before I leave for Switzerland.
Tl;dr If I have a Swiss Visa 'D' that starts in say end-Feb, can i apply for a French schengen visa C for early Jan ?
Or can I request for my Swiss Visa 'D' to start in early Jan but I do not enter Switzerland (i.e. use it for my travel to France then back to Singapore, before travelling again to Switzerland come end Feb)
I am not sure if the latter is allowed though.
