Sponsoring Niece and Nephew

Question details

I am a US citizen. Can I sponsor my niece who is 8 years old and nephew who is 4?

ANSWER

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.
