The PSB has 2 forms for you. One is called 'Accommodation Registration Form For Foreign Nationals' The other is called 'VISA/STAY PERMIT/RESIDENCE PERMIT APPLICATION FORM.

The PSB will get round to checking your address to ensure that you and your wife are in fact both living there. If you change address, they will check again.

The first form is for your local police station to complete. When that is done, you take that completed and stamped form along with the other form to the PSB. Originals and photocopies of various documentation belonging to you and to your wife will need to be submitted along with your application.

And last but not least, your wife will need to write a note informing the PSB that she wishes you to stay with her. So make sure she is on good terms with you!
