Hei,

I have two questions linked with sofi-number:
1) If these 3 months are over which sofi-number allowes to work in Netherlands, but i need to work one month more, is it possible to extend validity of SOFI for short period? If not, what could be the solution for working one month more?

2) From which moment this 3 months starts to count a) from the day, when I got the sofi-number
b) from the day I started working 

Thank you!
Mihkel
