@The_Real_Koteyka I really have no idea what you might be able to get shipped to Russia, so I'll list some examples of good laptops from Amazon, and other websites with the same laptops for similar prices, in case one of them works. There are a lot of laptops in the same performance category for around the same price though, so if one option doesn't work out, there are plenty of others.
The most important component in determining how well a given computer will run Sims 4 (and most games) is the graphics card, provided the other hardware is sufficient. An Nvidia 1650 will run all Sims 4 packs together on ultra graphics settings now, with some room to spare. That may or may not quite be true by the time the game is out of development—we don't know how demanding future expansion packs will be—but it should be a close call either way. An Nvidia 1660 ti is a bit of overkill and is also more expensive.
You don't need to worry as much about the other components. These days, any laptop that comes with at least a 1650 will have a processor that's more than strong enough for Sims 4; and at least 8 GB RAM, which is also enough for the game. Memory can be upgraded easily, if you decide it's necessary. Storage might be an issue, depending on what else you have planned for this computer, but most gaming laptops have room for a second drive if you want to install one yourself.
This laptop, at $600 U.S., is the cheapeast I've seen recently with a 1650. Its hard drive is small, but 256 GB is enough for Sims 4, mods and custom content, plus plenty of small apps and text documents. If your schoolwork is going to involve larger files stored locally though, that might not be enough. Still, you could add the second hard drive of your choice (the Acer has both a free NVMe slot and an empty 2.5" drive bay) for less money overall than the cost of the next cheapest laptops.

This MSI has the same specs as the Acer, minus the free NVMe slot, and is $700:

This Asus is the same, except with an equivalent processor:

If you can get this Lenovo, it would be an even better option for $700. It has a slightly stronger processor than the others, and a combination 256 GB SSD/1 TB HDD.

This Dell is $730 and has the same processor as the Lenovo, a 256 GB SSD, and a slightly faster graphics card.

These laptops have a 512 GB SSD and are $750. The HP has a stronger processor, although it wouldn't make a difference to Sims 4.

On the very high end, this laptop has a much stronger processor than the others, an Nvidia 1660 ti, 16 GB RAM, and a 512 GB SSD, in case you're wondering what $1,000 could buy you:
https://www.amazon.com/ASUS-IPS-Type-GeForce-Battery-TUF506IU-ES74/dp/B0865RZR9S/
This MSI has an even faster graphics card, although its other components are not as strong as the one above.
