That is a question you should ask your uncle to receive an answer.
Only US citizens can sponsor their parents to the US.
You must get someone to sponsor you, or you must submit proof of the source and ability to pay tuition, fees, and living expenses.
How do you sponsor a person coming from another country to the US
An immigrant can get another sponsor if the sponsor if the immigrant is on H1B. But the new sponsor need to file a new H1B for the immigrant.
You cannot sponsor someone who is already here illegally. You CAN sponsor them if they go home and apply for entry with a sponsor who will provide a home and/or a job.
The US citizen can sponsor his wife for a green card, not for US citizenship. Since he is currently unemployed, he will need to get a joint sponsor to complete an affidavit of support for his wife.
Yes.
A disability will not prevent a person from getting a visa. A disabled person is able to have a person to assist in the consulate. But the sponsor or applicant themselves would be liable for his medical expenses while in the US. Other than this the process is as the same for everyone else.
Sam is your uncle if you live in the US.
No. Your sponsor must already be a U.S. resident so you, as a non-resident, cannot sponsor yourself. Think if you have any relatives, friends, or employers who you can ask to sponsor you!
