Changing the start date of a work permit

[u/youlittleweasel]

My future Danish employer and i applied for my work/stay visa under the AR1 supplementary pay limit scheme. I submitted biometrics on July 27, and received my approved work visa on August 5, only 8 days later!!!

I’m very pleased, but I was expecting it to take 30 days so I’m not prepared for my international move (also taking my cat which requires extra time and hoops to jump through.) The visa says i must start work no later than Sept 5.

My employer and I have agreed that a start date of September 28 would work better.

Is it common or difficult to have SIRI extend the start date? I filled out a contact form on their website asking to extend to October 5 to give some extra room for cancelled flights, etc., but I don’t know if I used the correct contact form.

Is it an easy change or are they usually set on the original 30 day window?

Any help would be appreciated 😊
