you can't apply online for pr spouse sponsorship with owp. both have to be on paper. you need birth certs of yourself and all your family members/dependants either accompanying or not. for your sponsor, it is optional since you can choose to submit a copy of his passport or citizenship cert (refer to checklist). the questionnaire you answered online is just to determine your eligibility. you need to gather the missing documents/ correct errors in your first application then re-submit by mail to cpc-m
I do know that po, my question might be confusing but What I am asking is how to apply for an extension for my husband thru online.. cuz when I tried last night I have to answer questionnaires then the result was apply for spouse thing... which on the other hand I already apply for spouse sponsorship and owp. Thru paper . But got returned cuz they wanted the birth certificates of mine and family whether accompanying him or not,
