Thanks everyone for your fast replies. She is researching at a prestigious university in particle physics.

She has published several papers back in her home country, when she received her masters degree.

It sounds like the best thing to do is let the university she will be teaching at sponser her green card.

Hello everyone,

I am a US citizen. My sister recently came over to the USA on a F1 student visa. She is going through a PHD program that will take roughly 5-6 years.

I wanted to sponsor her green card. How would her already being here in the USA on a F1 visa affect her current visa if I sponsor her? Additionally, is the green card process the same for someone already in the USA with regards to processing time and cost?

Please let me know if there is any additional relevant information that would be helpful.

Thank You,
