The problem of illegal immigration to Russia has been covered frequently in the Russia news media and in official statements. You are, I am confident, capable of finding examples of that through internet searches.
I guarantee you that Putin and the Russian government are at least trying their best to secure Russia's borders while ours are wide open thanks to Biden.
There isn't any comparison between the damage being done to this country by illegal immigration as opposed to whatever negative effects in may be having in Russia.
