Right, it would take time for a new Russian expat to earn the trust that they don't secretly serve the old country, whether by intention or exploitation of any ongoing personal vulnerabilities they couldn't shake off in the escape. This limits their opportunities largely to routine maintenance, open source development, etc where they don't have the powers to hide their activities until they develop that trust over time.

During a conflict, it's generally better to be open to the initial waves of refugees, since these tend to be women, children, and professionals with valuable skills. As the conflict drags on though, you start seeing hardier but less skilled people who will also be much more persistent in trying to cross in while the rest of their family waits at home or in a refugee camp for their sponsorship to immigrate, for increasingly economic reasons rather than political violence and vulnerabilities.
