Yes it is true.

If she's in the Philippines, she pays for her visa & airfare in pesos.
If she's in Kuwait, she pays for her visa & airfare in Kuwaiti dinar
If she's in Korea, she pays for her visa & airfare in Korean won

... you get the drift ?

If she's also suggesting that you pay the airfare, and she'll re-imburse you when she arrives...... then think about kissing goodbye to that money.
