G. A father: Submit a copy of your birth certificate showing the names of both parents. Also submit a copy of your parents’ marriage certificate establishing that your father was married to your mother. If either your mother or father were previously married, submit copies of documents showing that each of the prior marriages was legally terminated
As other mentioned, finance is definitely a concern. Languages, cultural differences, weather... will have a larger impact on older people than younger people (like us). We are more tuned to adopt into new circumstances than older people. Some are able to adjust, some simply don’t. I’ve seen this a lot personally. I have two grandparents (my mom’s Dad and my Dad’s mom) who came to the US as LPRs and each of them lasted less than a year. They both abandoned their GCs and returned home and both told me “I wanted to die on my homeland, and not at a strange place”.
My wife and I both sponsored our parents. My wife’s parents have been in the US for 6-7 years and are doing generally ok. My Mom just got here last year so it’s yet to know but she’s pretty determined to make it work.
Fortunately for us, all of them have done relatively ok financially so they’re not that dependent on us financially, just mostly languages and social interactions, going to the doctors and shopping, that sort of things.
It’s a lot more than just “bring him here”.
However, it is also very rewarding. There is nothing like looking at grandma/grandpa having a good time with the kiddos. Those are moments that will be priceless for yourself and your kids to have interactions like that with the grandparents. As you mentioned, to make good memories. It will be worth it.
I’m assuming you are a USC since you brought your wife here on a K-1.
First you need the I-130 and read ALL of the instructions that accompany it. The questions you’ve asked here regarding money receipts suggest you haven’t read all of the instructions or you would know the answers. Read the instructions, then ask questions.
Can you afford to do this? It’s not just about the required income level to satisfy the I-864 requirements but your father will need healthcare, a place to live, food, etc. is he of working age? Can he speak English? What are his qualifications (if he is planning to work here)? If he’s too old to work or cannot get a job here, it could cost you a four-figure sum each month to keep him here.
