You should not reveal excessively too early your details to anyone and be diligent in your correspondence and take as much time as necessary in becoming acquainted with the individual you're keen on. Try not to give out exceptionally close to home subtleties like Visa, Adhaar and legal or personal information. Watch out for individuals who make undesirable inquiries or uncertain about their answers.
Make sure that always your first meet will not be alone until you know the person really well. When you plan to meet for the first time, try meeting him/her in public places like coffee shops and avoid meeting in any private place or hotel rooms. Also keep your trusted family member or friend informed before you initiate any such steps.
If you notice any cash trap just keep away, especially when individuals request cash be careful with such individuals and don't pay anything for visa purposes or any such issues. Never talk about budgetary issues with somebody you just met and scarcely know him/her. It could be exceedingly hazardous.
