Process of skipping a fiancee visa that I took.
(1) Enter the UK on a visitors visa. Getting past UKBA at the border is a challenging one and they will turn you back if they know a marriage is planned.
(2) Once a person is in the UK for one month, both partners can go to apply for the "Intent to Marry" being that Americans need this being non EU. The intent to marry is what to fiancee visa is actually for. UKBA advised me while I was there, that they can not stop a marriage from being performed in the UK if one is on a visitors visa if the intent was in place.
(3) After the Intent of marriage is ordered, there is a mandatory 16 day waiting period before a marriage can take place.
(4) Marriage is performed so skipping the fiancee visa.
(5) The non EU partner must return to the States before the 6 months to apply for the spouse visa. During this time of the application, the new couple in marriage can take there honeymoon in the states.
(6) If all documents are in order and nothing hidden, they will receive the spouse visa and return together.
*Notes* A fiancee visa allows the non EU partner to remain in the UK after marriage, doing it this way, at least the non EU has to come back to apply for the spouse visa.
Financially if done right, like I went through triple AAA for cheap flights, it comes out to the same price but instead of paying for the fiancee visa, the same money goes to the couples airflights round trip for the honeymoon during the wait of the spouse visa process.
