Death of a joint sponsor

[tiffanymarie12345 0]

Hello everyone I have a question regarding a joint sponsor. I’m currently filing K1 visa and my dad is going to be my joint sponsor since I do not meet the income requirement at all. We aren’t up to the financial stage since we didn’t even submit a petition but I am just thinking ahead. My dad has cancer and it has been progressing rapidly I really don’t have another option when it comes to joint sponsor. My mom and dad have been married for 30 years but my mom doesn’t work, only my dad does. If my fiancé is able to complete his interview and come over here, what would happen if my joint sponsor was to pass away? What happens if he passes away before he gets a green card? And what would happen if he was to pass away after my fiancé got his green card? I’m wondering if my mom could be my sponsor instead of my dad but she doesn’t work, she is just linked to my dads income since she is his spouse.. can anyone help me out here? I don’t mean to be morbid and assume that my dad will pass away, but I want to be prepared in the case that his condition gets worse. Has anyone had experience with this type of issue

I am new to all of this K1 stuff but I assume you send in your I129 with current info and plan on dad to do just fine.. if the unfortunate happens before the interview and I 134 I think you could use a more up to date sponsor. Perhaps mom as she will most likely be his heir.
