I'm not sure what you mean by POC. If by POC you mean Point of Contact, then you can call any sheriff's office, such as Link Removed
As you state, a non resident can apply to any sheriff's office in the state but you must apply in person, and you must have taken training from someone certified by a group acceptable to the MN BCA. I would suggest that you avoid Ramsey county. Their denial rate of 13.5% is over 10 times that of the rest of the state.
The fee is $100.
You'll also find out that Minnesota doesn't have a CCW permit. It's simply a Permit to Carry. We have no concealment requirement.
