People born in South Korea use the "All other countries" column. The chargeable country is usually the country of birth, with exceptions such as using a spouse's country of birth. If your priority date is earlier than the Final Action Date, a green card can be approved (or an immigrant visa issued) that month. If it is earlier than the Date for Filing, you have reached the point where documents can be submitted; for Form I-485 filed inside the United States, that is true only when USCIS has designated the Dates for Filing chart for that month. "C" means current (no date cutoff). "U" means no numbers are available that month.

Need to confirm whether your date is in?
Whether your priority date falls within this month's dates, and what to prepare first if it does, depends on the case.
These charts copy the dates from the State Department original and are not legal advice. Footnotes and conditions in the original are not reproduced here, so check the State Department and USCIS originals before you file.
