dear i am taking about AINP Family Stream, it syas you can sponsor parent, child , brother sister, niece, nephew then how you can spponsor only one person in one sponsorship commitment. when it comes to sponsorship one household can sponsor one sponsorship commitment but he can sponsor many (2-3, depending upon the financial position) candidates.
the law says you can sponsor your niece / nephews, if there are 4-5 nephews/nieces in one family then you will sposnor only on nephew / niece. its same as you can adopt your orphan niece / nephew. its one sponsorship commitment at one time but the candidates to be sponsored are can be more than one. last year my three cousins got the immigration under family sponsorship (Adoption). there was only one sponsorship commitment(Sponsor: Maternal Aunt) and the candidates were three.
Family Connection
I would like to sponsor my brother; my wife would like to sponsor her parents. Can we submit two family stream applications to the AINP?
No. There can only be one ongoing sponsorship commitment per household at a time. A second sponsorship could only be considered once the initial sponsorship commitment has been fulfilled.
