Prior permission to receive foreign contribution requires specific FC forms for different statutory channels, including foreign hospitality applications. Rule 3 requires applicants seeking prior permission to receive foreign contribution to use Form FC-1; applications for receipt under the proviso or alternate receipt provision must use Form FC-1A; and applications to accept foreign hospitality under the Act or related clause must use Form FC-2, thereby assigning specific prescribed forms to the distinct statutory pathways for foreign contribution or hospitality.
