Unless both parents come from a really dysfunctional family, this should never be the case.
Why? Many people immigrate away from their families for a variety of reasons other than them being “dysfunctional”. For example, economic opportunities.
I know a quite a few couples that moved from places with low economic opportunities to places with better opportunities, and one of the downsides is that they have to navigate parenting by themselves. It is a cost they are incurring to give their kids a higher probability of success when they grow up.
Yet:

That's not true. Our families may be away most of the time, but we have a constant rotation of our parents (and my wife's Giagia) coming to stay with us. When our second kid was born, I don't think we were by ourselves for the first six months. Even today, we get someone visiting us at least every other month.
> kids a higher probability of success when they grow up.
This is increasingly becoming something we are asking ourselves. I think our kids would benefit more from being able to grow up close to their families than in a place with a culture and values that we don't really share. For us (and me specially) living in Germany has been more of a "tolerable" than a "desirable" situation. With remote work becoming a reality, I think we can have our cake and eat it too.
That is not possible for many others.
None of those qualify as dysfunction in my book.
- "Older grandparents" is a sign that people are waiting too much to have their own kids.
- "Other family obligations", like what... Work? Perhaps we should rethink our globalized, modern economy that makes dual-income families a necessity. I really hope that by the time my kids get to have their kids, my wife and I are in condition to dedicate ourselves to help them as much as our own parents helped us.
- "Visa issues" is mostly an American thing, which unfortunately I also I am very familiar with (lived in the US before coming to Germany). The US is only going to sort this out after it solves the Milton Friedman dilemma: it can be either a country of Open Borders, or it can be a Welfare State. Until it tries to be both, it is doomed to these catastrophic policies.
- Does either side of the family have enough money to fund cross-country travel more than once a year for a week at a time?
My parents are retired/semi-retired. When they come, it's usually during the summer (here)
