Am I allow to stay in Romania to work?

Not automatically.  You will need to find an employer willing and able to hire you, just as any other non-EU national does, and they will have to obtain a work visa for you.  That virtually always means that you will return to your home country as the process (if successful) takes some time.

Hello karimbashira7,

Welcome to Expat.com

Kindly note that I have taken the initiative to create a new thread on the Romania forum to enhance the visibility of your query and help you in your search.

Now, may I inquire about the date you are expected to resume school?

All the best,

Its highly unlikely you'll find a job.  You'll need to speak Romanian at least to have any chance.
