Sponsor (Immigration)
In immigration, a sponsor is the US or Canadian citizen, permanent resident, or employer who files an application on behalf of a foreign national and accepts legal responsibilities for them, such as financial support or paying a required wage.
How it works by country
United States: a family sponsor files Form I-130 as the petitioner and usually signs an affidavit of support. An employer sponsor files a work petition such as the H-1B or I-140.
Canada: citizens and permanent residents can sponsor a spouse, partner, or dependent child and sign a sponsorship undertaking promising support for a set number of years. Employers support workers through an LMIA or an employer-specific offer. Parents and grandparents intake has been paused since July 2026.
Mexico: family members can support a residence application through family unity. See US family immigration and Canada family sponsorship.
Frequently asked questions
Can a friend sponsor me?
Not as the main petitioner. In the US, a friend can act as a joint sponsor for the affidavit of support only.
Does an employer have to sponsor me for a work visa?
For most US work visas, yes. Some options, like the O-1 through an agent, still need a US petitioner.
Is a sponsor the same as a petitioner?
In US family cases, usually yes. The sponsor files the petition and supports the immigrant.
