I would say that the first step is to go to page 38 of your passports. It says three things. It says to read the travel advisory we put on our website, register if you are going to go abroad so we know where you are and reach out in case of need.
Those three Rs are the best advice I can give. As you saw yesterday, it's changing by the hour, so the best way is to be connected, be informed and reach out for assistance.
