My oath ceremony is in a few days. However, I need to go visit my mother in my home country soon to help with some of her health issues. I don’t have definitive dates yet, but know it will be in the near future. It is a lengthy process to get the US passport and will need to get a visa back to my home country after. I have missed one oath ceremony before due to missing the letter in mail. What is the best option here? Thank you in advance.
