Saving option advice for a F1 student

bwspot

Few years ago my sister left her native country and became F1 visa student.
She has been in USA for few years already and seems like she will stay longer then expected and study. During the time here on F1 visa student status, she cannot work and therefore cannot save any money for the SS retirement. Are there any options to prepare for the retirement in case she stays in the USA and gets the green card later via my sponsorship? I filed for her few years ago, but cases like that take forever. She is afraid that she will end up with nothing? Her boyfriend and I are willing to help her and give her some money monthly. She has Us social security card if this matters. Not use if 401k or IRA or anything else is an option?
Your help would be greatly appreciated.
thx

This is a generally a UK based site though a lot of UK Ex-patriots contribute from around the world.

I thought F1 meant Formula 1. Authorities throughout the world are clamping down on the student route to migration where the once student eventually vanishes. There may be avenues for employment and career progress in other countries for successful students.
