You can obtain full information about the procedures, and some advice about the relevant procedures by downloading the section of The FA Handbook that covers these matches.
Permission is not needed for one-off matches against teams from Scotland, Northern Ireland and Wales although documentation IS required for matches against teams from the Republic of Ireland and other FIFA countries.
In addition, an application to participate in a match or a series of matches against members of another National Association involving players of school age shall be required to demonstrate that all such players have received the necessary permission from their head teacher before The Association will give consent.
To play one or more matches against foreign oppostition, whether at home or abroad, clubs must send an application form to The Football Association at least 28 days in advance, although we recommend you apply as early as possible.
