Can I get a re-entry permit after obtaining my Non-O (retirement) visa?

The user is set to receive a Non-O (retirement) visa valid for 90 days with an option for year extensions. They inquire about the possibility of obtaining a re-entry permit for travel to Siem Reap in December. A commenter clarifies that once the user has the new 90-day stamp, they can purchase a re-entry permit, but it will only cover that 90-day duration, necessitating a return before the stamp expires to maintain eligibility for the year extension.
