I trying to help my brother prove spousal sponsorship in Canada. Any and all advice is much appreciated. He has been living in Canada for 4 years ago from the U.S. and met his wife within a few months of moving. He was married 2 years ago. He originally moved to Vancouver to pursue a masters degree. He has finished his masters and is working full time. He received a letter recently calling he and his wife in for an interview for his permanent residency and their spousal sponsorship. There is doubt by Canada on how genuine their relationship is. Has anyone gone through this or heard of this?
