Friends,

My mom is here on b-2 (visitor visa). thinking of applying for TPS.
Q1. What happens to her B-2 visa that is for 5 years?

Q2. TPS application requires that you prove continuous physical presence/continuous residence. what documents might be help prove that? I mean she is been living with me and hence no bank records, vehicle registration etc..etc.. that Form I-821 says could be used to prove such.

Thanks.
