Coronavirus and your visa
According to the website of the Dutch Immigration Service (www.ind.nl) any visa extension request will be assessed on an individual basis. This also applies to requests from people who cannot return to China because of the consequences of the corona virus. Individual circumstances are included in the assessment. The current situation that some airlines will no longer fly to China is a factor in the decision-making process. Should airlines fly to China, this may be a reason not to renew the visa. After all, in that case there is an option to return to China. The presence of the coronavirus itself does not automatically lead to a visa extension.
So if your visa needs extension, you have to have to submit an application for an extension.
