Can we go for Flag Polling at Border to convert Visitor to Open Work Permit

[Kamal Vadla]

Hi All,
I am on Visitor Visa currently. I want to go to Point Roberts Border to flag poll. I have applied for SOWP in Dec 2021. But till now, No update on that. My Visitor Visa time is getting expired in June 2022.
Can i go for Flag Polling at Point Roberts Border to change my Visitor Visa to Open Work Permit? Is it legal ? If any body know the timings at border, Please share.
