Hi. Just wondering if there is a hidden program am not aware of to sponsor my sister and her son. I found this program on Canada.ca website (Sponsor Relatives) but she doesn't qualify to it. Any suggestion would be appreciated. Thanks!!!
As said above, there are no hidden programs. All immigration programs are published on the IRCC web site.
The only option you have to sponsor your sister is if you are single, have no children, both of your parents are deceased and you have no other family members in Canada, then you can sponsor her under the Lonely Canadian program which takes approximately three years.
Otherwise she has to qualify on her own through an economic immigration stream.
