Just a recommendation, apply for and get your passports now. Or renew them to get another 10 years.
You need it for international travel.
If you wait, the new administration will likely put all kinds of new requirements in place to get a passport. For example, have all your vaccines up to date? Do you pass a full and complete background check? etc.
Now is your window of opportunity.
So how do you get it? Its not that hard, just takes following some steps.
