My grandmother overstayed her tourist visa for 2 years. She has came back to her home country (Poland) about 5 years ago and has gotten a 10 year bar on her visa. She is now living in Poland. I am trying to explore her options on how she can legally come back to the United States. Does she qualify for the I-601 Waiver? What are her other options? How long will the process take? Thank you in advance.Her daughter is a US Citizen and has been living here for 12 years. I also wanted to know what is the denial rate.
