I assume you mean staying abroad while keeping working for the Russian company.
You need to understand the scale. Just today Yandex (one of the largest IT companies in Russia, think “Russian Google”) has announced[0] they are at risk of default. That’s 10 000 people, and Yandex is not the only large IT company.
Companies like EPAM also have plans to evacuate people, that’s north of 30k people in Ukraine, Belarus and Russia and it is not clear how many layoffs there will be.
