I just read this below, from an immigration website. My question is, when re-entering the US from overseas travel (not Mexico and Canada), do I just have to show my green card and then is let in, or do I have to, as stated in below quote "apply for readmission." What does "apply for readmission" mean? Do I have to fill out some sort of paperwork or form, or is it merely the act of presenting my green card with my foreign passport I have "applied for readmission" into the US?
"If you are a lawful permanent resident (immigrant) returning to the United States from a visit abroad of less than a year, you may apply for readmission by presenting your Permanent Resident Card ("Green Card") to the immigration authorities at a port of entry."
