Some Private Colleges accept Masters grad. But better get your phd after masters. if you'd like to be a lecturer.

10 years ago, you can teach undergrad with Masters degree in all IPTA,
nowadays, you need a phd to teach undergrads in some courses,
10 years later, it may become mandatory to have phd to teach undergrads,

I don't really think you can secure a lecturer job for the next 30 years with a Masters Degree
