Next week bata mailey paid off campus internship suru gardai chhu. Ani ahiley ko college ko kaam pani hunchha tara I will not be working any hours for now. The only reason i am keeping on campus job chahi so I can work extra hours during christmas break. 

During Christmas break mailey kati hour kaam garna pauchu duitai kaam combine garera? I know school week ma i can only work 20 hours combined.  Mero saathi haru ley christmas break ma duitai thauma 40 hours each garna paincha bhanchan tara no one is certain about it. Sajha bashi kasailai kehi thaha chha bhaney yeso bhandinu paryo. Dhanyabad.

 20+ during school break including winter and summer. Doesn't matter if your work over time.
It's upto you how much you wanna work.  
To confirm, talk to your international student office.

 So 20+ hours meaning 40 hours each job or 40 hours combined?

You can work more than 40 hrs combined or 40 hours each if you can. Just to be on safe side, talk to your international student advisor. 

 tenacious is right, the rule says that you may work more than 20 hours but doesn't say anything about the limit. according to my school's international advisor, i can work 100 hours if I like/can during my OPT and I believe the same applies to work during the break.

 Ghanta marne bhaye junta haru le.........!  Yeah you can work upto 40 hrs oncampus.....rest everyone knows....
