Native English American needed for six months to teach ESL to a wealthy family in Colombia/Mexico/Venezuela/Russi. All expenses paid and you will earn $900 per day as live-in teacher for investor soon to relocate to America on EB5 program. Send your resume, photo, and passport scan to Ethan at VIPESLRecruiters@gmail/hotmail/yahoo/msn.com
You will then get a telephone interview allegedly to evaluate your English and you will be selected within a day or two. They then offer you a $10,000 cas bonus if you can fly to the destination within a few days. They will even send you a contract that puts all their promises in writing, but they say it is not valid unless signed in their country.
When you fly over to that country the "family lawyer" will meet you at the airport and have dinner with you and help you check into a hotel. They will even give you a phony business card. The "lawyer" then asks for your passport to process you with the local authorities. In a day you will get a call that says someone with our name is a wanted fugitive and they need your national ID (or social security number) to prove it is not you or you will be arrested and jailed pending extradition!
Of course people are terrified and will readily give the "lawyer" any information he wants. They will then research your family online and if your family is well-off (living in a $500,000 home, or having a luxury car registered is enough for them) a fake detective will show up and say he has to take you for fingerprints to make sure you are not the fugitive. People want to profess and prove their innocence and go with the detective. You have just become a hostage in Colombia or Mexico, or Dubai and your family is shaken down for $500,000 or more. If you do not come from a wealthy family, you will be told that there is an emergency and your services are no longer required. But in 6 months you will be contacted by the police about the $20,000 of jewlery or other merchandise purchased in your name. Of course, you will not even think th ecredit card fraud has anything to do with your trip six months ago.
Yes this is a sophisticated scam but it is more common than you think. Over 1,200 ESL/TEFL teachers were victims of this VIP Tutoring scam in 2016 according to Interpol.
