It means that something is a certain way right now but it could change in the future. As in, "You can stay with us for the time being." This means that other things may happen in the future to prevent you from staying but right now you can stay. I hope that made sense. :)

For the time being = it will be like that for a short period of time

Hi! I am happy to help you learn some of the very fine points of American English. Things that you can really only learn from the average American speaker. If you think this might be good, please add me to Skype: ron.jenkins86 and we can chat and see if we can help each other. Thanks for reading me. I hope you have a great evening! --- Ron
