She filed I-601 for vaccine waiver, along with documents to support extreme hardship and a statement of discretion. Her green card application was during COVID so that may have impacted the timeline. She filed May 2020 and got her green card May 2021. Her I-601 was approved with her I-485/I-130 three days after her interview, and she received her green card one week after the interview. They asked her a few question about her beliefs and documents she submitted during the interview, but didn't focus too much time on that form. I think the key to her getting her I-601 approved was LOTS of documentation: years worth of vaccine waivers, affidavit letters from others, a strong personal statement, and medical records.
