Compared with 2020，the total number of immigrants to Germany increased significantly in 2021. The German government has made the promotion of COVID-19 vaccination its top priority as the epidemic continues and the prevention and control process becomes regular. In order to speed up the vaccination process，Germany introduced restrictive rules such as “2G”，“2G+”，“3G” and “3G+”. Immigrant groups have lower vaccination rates than native Germans，mainly due to lack of language knowledge and fear of being deported for revealing their status. After the new government took office，Germany’s immigration policy has become more relaxed，and Germany’s attractiveness to professional and skilled immigrants has been further strengthened. A large number of illegal refugees crossed the Polish border into Germany，bringing difficulties to Germany’s immigration governance. The ongoing epidemic has promoted the electronic process of German immigration management，and has also changed people’s social psychology. In the future，Germany may face the enormous pressure brought by the Ukrainian war refugees.
