I am happy to provide a letter for your Immigration Agent or a local or international Department of Immigration after I have received the NOIM and payment.
My immigration letter is on my own letterhead showing that I am an Authorised Marriage Celebrant , includes the following:
the date NOIM lodged,
date and place of planned marriage
confirmation of payment
I do not however issue a letter until payment is made as this offers a small guarantee that the matter is genuine and reassures the departments of same.
A copy of the NOIM is not required for the Australian immigration but if one is issued,, it is stamped as a copy and certain parts may be redacted for privacy and security.
