:?:<<<PSW and EU country Residence Permit>>&g

Hi

I have question that does it make any difference or is there any restriction/condition to acquire PSW and a residence permit for another EU country as I works in UK but due to joint business with my friend ,I have resident permit of another EU country on the basis of business.

Could it be problem to travel frequently for 2-3days(once every month to that EU country)?

Any expert advice will be highly appreciated.

Thanks
