Im holding a Non-B visa (single entry), I need to fly out for a couple days, im aware that i need to do re-entry at the airport before departure, so does anyone know how long will this process takes? TIA.
TLDR : Answer Summary
The re-entry process for a Non-B visa typically takes about 10 minutes, but it can vary depending on the number of people ahead of you. It is also possible to obtain the re-entry permit at your local immigration office in advance.
