6. Failing to inform the company of your credit card about your plans to travel
Companies who provide services for credit cards usually flag transactions that are foreign to avoid cases of fraud and other card-based crimes. This may result to them freezing your account. To avoid this incident, ensure you let your company know of your travel plans before the time. While in the process of informing them, also check to know if there is a fee attached to foreign transactions so that there would not be any unexpected deductions or changes.
