Well I am not sure what the laws are in Nigeria. I am assumeing you mean to leave there someday and come to america. Be warned that your vast nursing experience and license does not gaurantee that you will be allowed to work as a nurse here. I know of doctors from other countries who had to settle for taking the RN exam because their MD license did not carry over. I also know that many RN's in other countries end up having to work as LVN/LPN's because the training and education is different. In any case there must be other nursing positions open to you that you can go to. Why stay where you are not paid? you aren't losing you will be gaining. Also does your government have a labor support advocacy group? You might have to report your employer to these groups. You have to eat and support your family. That takes money. You have not been paid for 6 months? It is doubtful you will be paid at all. Good Luck in your future.
