The COVID-19 epidemic has brought huge impacts on global health，economy and international relations，and has also extensively affected cross-border population mobility. In response to the epidemic，EU countries have intermittently closed their borders and restricted the gathering and movement of people since March 2020. As a result，the number of asylum-seeking refugees entering Europe has dropped significantly，and the mobility of long-term migrants and short-term migrant workers has also decreased. Irregular migrants are widespread in European countries. During the epidmic，European countries have adopted “push” “pull” “block” “harmony” four combined strategies in immigration management. These strategies effectively alleviate the negative impacts of international population movement on the political，economic，and social etc.；however，a series of problems occurs，including humanitarian crisis，immigrants and refugees integration difficulties.The tightening of immigration policy has become the convergent choice of political parties in various countries，and the cracks in the cooperation between EU countries have increased in the resettlement of refugees. Removing the “politicization” of the immigration issue and restoring the economy as soon as possible to lay a solid foundation for the integration of immigrants have become the necessary measures for European immigration management.
