Trump is going to declare a National Emergency so the military can come to your home and check your immigration status without a warrant.
Make sure you have a valid birth certificate, social security card, state ID etc. This will be important especially if you have a parent who was an immigrant (like my Mom) & or have a Hispanic last name.
Women make sure you know where your marriage certificates, death certificates, divorce papers are as proof of change to maiden name.
@VeganHiker good plan, have multiple access points to use as necessary.
