A Canadian citizen can sponsor a spouse or partner while living abroad, so you can sponsor your husband while living in Kosovo.
But you will have to prove that you will go to Canada to live once he gets the PR visa.
As well, you do not need an income to sponsor a spouse, but you do need to show the visa officer that the two of you will be able to support yourselves in Canada. So think of how you two would live once in Canada. Do you have relatives in Canada who could let you live with them while you look for jobs? Or would help support you in some other way? If you do, get these relatives to write an affidavit or letter stating they will help you, and include it in your application.
