In the U.S., more immigrants with children are still in their first marriage

Your post, and the upvotes it's getting, are the second wave :)

HN commenters (or the stereotype thereof) who are married would actually be more likely to be in stable marriages, and thus able to weigh first-hand the relative likelihood of a stable/happy correlation.

I don't see anyone saying this. Instead the claim is: when divorce is a cultural taboo, people are more likely to stick in an unhappy or even abusive marriage. This claim seems pretty uncontroversial, but at any rate it is a positive claim (not normative) whose accuracy can be judged by empirical data.

Immigrants can come from anywhere, and different countries have different views on divorce. Some countries are much less strict than the US on this matter.

Plus culture where freedom, independence and success are more valued than institute of marriage, interdependence and family life.

Is happiness the most important goal? Could one have other aims in life beyond the pursuit of happiness?

Had that happen with my parents. We immigrated when I was a teen, and just 4 years later my parents divorced. To people on the outside it seemed completely out of nowhere. But growing up with them, it was painfully obvious (in retrospect) that they kept it all together not by trying to actually solve problems or work things out, but by holding it all together just on pure will. It could've been held forever if everything else was stable, but immigration process and the experience of adapting to a new country is anything but stable.

While it sounds bad, I don't think of it as a tragic experience, and I don't wish that it had never happened. I am not happy that it happened either, but it was bound to eventually happen one way or another. Either that or one (or both of them) would just settle with being unhappy and miserable until the last days, being constantly anxious that one day that bridge held by duct tape would collapse.

Marriage is a tool for survival in more parts of the world than where it isn't. People around the world have more miseries to care other than marriage.

Immigration itself is a filter for education, wit, and wealth, and, sometimes, even physical fittness, and health.

By the definition, if both husband, and wife pass that, that's a very rare, lucky marriage.

Russia has huge divorce rates, but Russian immigration much lower.

Russians marry late back in Russia, but in mid-twenties, and early twenties marriage is commong among people I met.

There were probably more women from Russia I knew in technical occupations in the West than all other women in engineering I knew alltogether.

Think of it, if you were a woman, and was from the start aiming at studying for long 6 years, having harsh early career, and enduring hardship of living as a recent immigrant, you wouldn't be getting a husband whom you need to pull.

From my not-terribly-informed position, it looks more to me like this is part of the ongoing power struggle in the conservative movement. They recently had fairly poor election results, and this looks more to me like an attempt by this group to reverse their looming demographic challenges by at least trying to reach out to immigrant groups.
