What is the ruling on a girl traveling alone to work abroad, and what is the ruling on the money earned from this work?

A Muslim woman's travel for work or other purposes is not permissible except with a mahram. If she is young, the sin is greater. If it is a journey for permanent residence and work, the matter is more serious. As for the ruling on the money earned from this work, if the work itself is impermissible, then the money is unlawful. However, if the work is permissible, then the money is lawful, even if the woman is sinful for her journey.
