If you are looking for an overseas jobs then just keep in mind my following steps:-
1) Email - Whenever you get a mail regarding job opening in an overseas company do the following steps
- Check who has send you the mail.
- Ask for company website by replying to that mail.
- Get as much information as you can about the company.
Normally scam placements ask for any kind of money, when you pay that money they will just hide-off. A scam placement doesn't provide company details (in which the job opening is) because they are scam and really doesn’t have any details of the company. If you want to know whether the placement is fraud or not just ask for company websites (in which the job opening is) or details. If they are providing the same than it’s good for you to take the information about the company or if they are not providing any relevant information about the company than just don't give any money without inspections.
