You can apply for a green card easily enough - but the chances of getting one are slim to zero. As is a visa for anything other than a holiday
The one avenue is that IF she has a skill that is scarce in the US, AND can find a job (without visiting the US - she cannot look for work whilst on holiday in the US, and will be refused admission if she as much as hints at it) from an employer willing to sponsor her, then a visa MAY be possible.
Consult a US Immigration lawyer, and be prepared to pay - a lot.
