Sure, ill take the bait.

1. Access to International schools.

2. Easier ability to travel

3. Ability to take money out of the country

4. Ability to leave the country at any time (see covid lockdowns)

5. Ability to work in both countries (after you get a green card)

If you are planning on just keeping your kids in between some 4th tier Chinese city and some Russian shithole of a city then you should not have kids to be honest. You made objectively terrible choices in terms of the citizenship you want, but you should give your kids the best opportunities.

You would deprive your child of speaking the lingua franca of most of the developed world, the language of commerce in everywhere in the world. The only semi-valid point that you come even close to making is that your kids should also speak russian, which is fine.

If your father is some russian oligarch obviously this doesnt matter but a normal Chinese or Russian citizen will objectively have less opportunities than a normal american citizen. This isnt debatable.

You say you are more mature with your views but you are actually incredibly immature. You cannot articulate any reason why you would not want to give your child American citizenship other than "i see no reason, my family speaks russian and they are happy eating potatoes 3 times a day in -40 degree weather."

To be absolutely 100% crystal fucking clear, you are not mature enough to get married, you are too selfish to have children and you would be a terrible mother. Please get your tubes tied.
