QUESTION ABOUT SINGLE ENTRY VISA

Hello colleagues,

Am an African. I have been granted a D visa. However the visa sticker indicates that:

Number of entries: single entry visa (01)

Valid for: Norway

Valid from 23rd July to 2 September 2023.

I will be a student in Norway, however i have a workshop in Switzerland from the 22nd August 2023 to 2nd September 2023. Will i be allowed to use this visa to go to Switzerland for the workshop? the workshop is 9 days. Then after the workshop, will they allow me to come back to Norway after the workshop?


I have not yet got the residence card, but i have a workshop in Switzerland, will it be possible for me to go to Switzerland and then back to Norway with such a visa?

Am confused

Thanks
