The new Green Card rules for 2020

The new green card rules for 2020 include:

- Failing to admit you’re an immigrant on your tax returns or failing to report some of your income could get you deported

Men between the ages of 18 and 25 who hold a green card must register with the U.S. Selective Service; failure to do so could lead to deportation

An extended overseas vacation could cost someone their green card - it could be considered "abandonment" of the green card
Not knowing what the new rules are could get someone holding a green card kicked out of the United States for good.
