My mom filed an I-360 (petition for widow of US citizen) and an I-601A (for unalwful entry). She has her consular interview abroad in her home country. She EWI, entered without inspection. She has a history of mental illness and can't remember the specific details of where she crossed, it was over 30 years ago, she just knows that it was without inspection. Will the immigration officer ask very specific questions about her entry, and is saying that she entered without inspection enough? If anyone had experience with this interview and this situation, I'd appreciate your help.
