Hi everyone,
Finally I collected all of my papers for spouse sponsoring and I would like to send them ... right now

But Im confused about the fees - I think it's a new thing, and it changed with the new application forms. I understand that the fee is for Principal Applicant is $550 and for the spouse (or common-law partner) is $550. What should I do with the Right of Permanent Residence Fee - which is $490. (They STRONGLY recommend pay this fee although it should be request just at the end of the process when they application is approved.) Is it really worth to pay everything together?
Yes tikestba, pay everything together like what CharlieD said..
Sponsor - 75
Principal applicant - 475
RPRF - 490
Total - $1,040.00....
this may help make your processing time shorter (CIC don't have to send you a letter/correspondence asking u to pay the RPRF...which in some cases letters via snail mail gets delayed in delivery). I had friends who paid RPRF after the medical req (MR) and it took an extra 2 months for their application to get new updates.
