Vistor Visa extension and later CoS for Greencard

[sachingshetti]

Hi 

My Mon B2 visa is expiring on Jan 9th and I was planning to apply for an Extension due to Covid. Do we need to show any documents for extension?  secondly, I am awaiting my citizenship in the next few months, Can I sponsor my mom once I have extended her B2 stay

She should not apply for a B2 extension of stay. B2 extension of stay requires a statement about her plans to leave the US, and it sounds like you guys don't plan for her to leave, so the statement would be a lie. If she waits until you become a citizen, she can apply for Adjustment of Status to get a green card. She does not have to be in status to do Adjustment of Status in her category.
