Eight men arrested just before a number of "sham" wedding ceremonies were due to take place in Gretna travelled from all over England.
Immigration officials say the areas include Bradford, Manchester, Southall, Blackburn and Wolverhampton.
There were five would-be grooms and three guests who were due to attend the ceremonies.
Six of the men have been detained pending their removal from the UK, while the remaining two must report regularly to the Home Office while their pending immigration cases are concluded.
The intended brides from the Czech Republic, Romania and the UK were interviewed and released.
