Such a refusal is relevant for companies from Russia. In one of our articles on trends in recruiting, we wrote that the desire to
relocate has grown many times over in comparison with previous years in the tech sphere. This is due to the pandemic, the economic crisis, and the traditional "search for a better life."
It's rather hard to handle such a refusal, unless, of course, in the foreseeable future you are not planning to open a new office somewhere in Germany :)
