I just stumbled in this links while searching for info in getting married in Anglican church.
Q. What happens if one of us is a foreign national?
A/ If one is a national of country outside Canada, Australia, New Zealand, South Africa, the EU or USA The Church has a responsibility to conduct marriages which will be recognised in the country the bride or groom comes from. This is done for the couple's benefit not just for bureaucracy. Therefore, the Faculty Office strongly recommends that these marriages should be done by Common Licence rather than banns and some dioceses ask the person to obtain from the relevant embassy or consulate a letter saying their marriage will be recognized. There are now stricter rules applied by the Civil Registry office to prevent "sham" marriages.

This predict a long processing?
