學期間part-time CPT實習，可以同時做on campus job嗎？分別都是20 hrs per week

請問有人有在學期間，同時做 part-time CPT 和 on-campus job 的經驗嗎？同時領兩份薪水，而且總工作時數變成40小時（分別20小時），請問日後的簽證會出問題嗎？

小弟目前就讀 Master，正在做 Fall semester 校外 part-time 實習，每週20小時，而近期獲得原本實驗室教授提供的 on-campus job 機會，也是每週20小時。由於擔心同時做 off-campus & on-campus work 會影響到日後申請 OPT 或 H1B 等簽證，不確定該不該接下這份 on campus job。由於本來就在該實驗室做研究，就算不簽 on campus 合約、不拿薪水，還是會繼續做研究，所以這份薪水更像是 bonus，若有影響到學生簽證或者日後的工作簽證的話，還是傾向不接了
以下是學的回信，總共兩封：
Thank you for your email. While on-campus and off-campus are two separate work authorizations, there is no clear immigration regulation stating that students can or can not work on both. However, the purpose of F-1 status is pursuing academic study in the U.S. Even though your schedule might permit doing both on-campus and off-campus employment, in the future, immigration could potentially question the intention of focusing on working rather than studying. OGS cautions students of the potential risk of working on both employments during the school year.  

Thanks for your email. CPT work authorization and on campus work authorization should not be conflated.  CPT is academic/educational activity.  On-campus employment is something different.  However, please remember that your primary intent must always clearly be that of a full-time student, not a full-time or nearly full-time worker in the U.S.

從學校的回信來看，似乎兩者是不衝突的，但沒有明確的規定這個情況，因此想詢問一下版上有人有類似的經驗嗎？謝謝大家！

我也好奇这种情况!
