Singapore Love Links is a great website to find single girls or guys in Singapore.
You'll start off by creating your dating profile. It should take less than 10 minutes altogether. You will answer a set of questions about yourself and add pictures.
Next, you can perform searches by using either the Basic or Advanced searching tools. Advanced searches allow you to define lots of details about the kind of people you're looking for.
A free membership will allow you to use almost all the features of the website. By upgrading, you can contact all the people that you're interested in, and free members will be able to contact you as well.
AsianDating.com is another service that has tons of Asian singles. I did a search and found lots of women from Singapore.
AsianDating and SingaporeLoveLinks were developed by the same company, so both websites look similar and have all the same features.
If you want to check out AsianDating, take a few minutes and set up a free account. You'll have full access to the search menus, so you can look within Singapore or expand your search to include other Asian countries.
