Some kind of formal certificate signed by a rabbi showing participation in a lifecycle event is great to have as well. If you are a Jew by choice or have one in your fam, be sure your conversion certificate is signed by at least one rabbi who has had conversions accepted in Israel, although they are finally getting better about this. Also the kids! Bnai Mitzvah certs, brit milah/brit bat certificates, whatever is available to you. Keep in one place that you can stick in a suitcase fast. Hard copies of all of your prescriptions, and backup supply. If you can? Burner phone. - with love to my fam from your internet bubbie
