I thought I was using a website engaged by the USA government to process visa application. After I made payment and a couple of emails, i got suspicious and questioned the scammers. They have not reverted to me since. I lost about sgd 120.

The suspicious website is www.usa-visagov.com. I did some search on the topic and the usa visa scam is one of the more common internet scams globally. i was careless and did not check it out properly.
