ICACR 2020 Conference is not authorized to assist with the VISA process. The invitation letter from the organizing committees will be sent upon the request only when you register successfully, which may help but cannot guarantee you a visa.
In case of refusal of visas, the ICACR 2020 conference will not be held responsible if you are requested to cancel your participation to the conference.
