Sponsoring Niece and Nephew
I am a US citizen. Can I sponsor my niece who is 8 years old and nephew who is 4?
It depends upon how we define the term "sponsor." If you mean can you apply for their green cards, the answer is no. If you mean can you provide an affidavit of support for them to visit or study in USA, the answer is yes.
Thank you much. The information provided was very helpful.
