I, too, received an email from bilingual-institute.com asking me to apply to their school. I thought I'd submit my resume to the Teachers International Organization just to see what happened, and, then, I was told that two schools were very interested in hiring me. That's when I went on the hunt. I traced the email header of the email from the bilingual-institute by way of this website http://www.ip2location.com/emailtracer.aspx

(I learned of this from a previous post by Rock G. Bedard: http://www.eslteachersboard.com/cgi-bin/scamalerts/index.pl?read=2378)

It appears that the email was sent from the Dominican Republic. I then traced the 2nd email I received, the email from the Teachers International Organization, and it too was sent from the Dominican Republic.

In fact, they have the exact same IP address 201.229.248.144

As of yet, I know not of any recruiters of English teachers in the Dominican Republic.

Peace!
