I have been in another country as a visiting researcher to participate in a research project of which my university is a partner. It was agreed by word of mouth that I would be paid soon after arrival. Several months later I am back home and still have not received the money.
So far, the host researcher has made the formal arrangements in the foreign country. He told me that the delays are due to internal problems at his (very reputable) university. Regardless of the reasons he has no solution, I travelled from a very poor country to earn some money and this was a very hard blow to my family's finances.
What are some alternatives I could try to solve this problem soon?
