Hi all, I have applied for 309/100 visa couple of months ago and provided the 40sp form(Sponsorship for a partner to migrate to Australia) which was filled by my partner(Sponsor). Now i have received an IMMI request that to provide 'e-sponsorship form : Sponsorship by a partner to migrate to Australia' Is the requested e-sponsorship form is same as the 40sp online form ? If no could you please explain me what is the e-sponsorship form and where can we get that? Thanks in advance
