Hello there. Hope you are doing good. I assume you are talking about applying to master degree programmes since nothing is mentioned in your query. I would like to tell you that yes you can apply for further studies by giving provisional degree as a proof of under graduation. Usually, it takes time in many universities to get the degree. So, you need not worry. You can simple use your provisional degree and continue your admission process.

I hope you found this answer helpful. God luck for your future.
