The Sponsor is a person that provides funds.
Being a sponsor carries important and long-lasting responsibilities, this person must guarantee the full financial responsibility of the immigrant candidate until she or him become a US citizen or until they prove that they worked for 40 quarters or 10 years.
A sponsor of any immigrant candidate must be at least 21 years of age and a United States citizen or permanent resident. The sponsor must maintain a primary address in the United States or a territory of the United States.
During the process, the sponsor must verify sufficient income and net worth to support himself and other family members, as well as the immigrant applicant.
This economic responsibility comes into effect in the event that the immigrant cannot support themselves financially. The government with this seeks that the foreigner does NOT become an economic burden on the government.
