If you are traveling long-term or without a fixed plan using one-way tickets , you may be required to show proof of onward travel in order to obtain a visa or even to board your plane.
Many countries require that you show a ticket for onward travel at immigration, or even before boarding your arriving flight, showing that you will leave their country within the required time limits. In some cases, travelers have been denied access to their flight or had to buy a very expensive last-minute return ticket which they might never use it, to show this proof. Another option is to buy a refundable ticket and then cash it in, but this can be an expensive hassle and must be done quickly.
Is there any other way to solve this problem ? The answer is YES!.
