On their e-mail to me on June 1st 2016 they have asked for:
1. New Generic Application Form for Permanent Residence- IMM0008 form.
2. Schedule A – Background/Declaration [IMM 5669] .Please complete and then print the forms. All forms must be signed. You need to update the above documents even if they have already been submitted. Please declare personal history and addresses since the age of 18 without any gaps in dates.
3. New Additional Family Information Form IMM5406 .
4. Recently issued new police certificate from any other country where you would have been for more than 6 months, since the age of 18. All police certificates must be originals.
5. An update of the history of your relationship/periods of cohabitation.
I have sent my response on July 1st, and no feedback yet.
I don't have any connections out of this forum going through the same experience, I hope someone here who been through it and then got their PPR e-mail would let us know of the expected time line.
