Next, identify your country of nationality (If you are claiming chargeability from a country other than China, India, Mexico or Philippines, then you should refer to the first column, labeled “All Chargeability Areas Except Those Listed.”) The cell that represents your Preference Category and Country of Nationality will contain either a date or a letter. If a cell is marked “C” that means that the Priority Date is current in that Category and visa numbers are available. If a cell is marked “U” it means that no visas are available for the rest of the fiscal year (which ends on September 30). If a date appears in the cell, then that date signifies the visa “cut-off” date. Applicants must have a Priority Date that falls before the date listed in the cell in order to apply for a Green Card.
