В Сингапуре Вам еще надо получить разрешение Республики на женитьбу на ее гражданке
Согласно этому
http://en.wikipedia.org/wiki/Matrimonial_law_of_Singapore "Foreigners, permanent residents and mixed marriages Foreigners marrying in Singapore may require approval from Ministry of Manpower, depending on the type of visa they are on. Failure to get such an approval, when needed, may result in being deported and permanently banned from entering Singapore and be on the Fugitive List with AFIS details. For couples who are not Singapore citizens or Permanent Residents, at least one of the parties to the intended marriage must be physically present in Singapore for at least 15 days preceding the date of the notice."
- разрешение зависит от типа визы
А если мы решим расписаться в России, то мне опять потребуется разрешение от Сингапура?
