Yes, you can do a regular M.Tech and a work-from-home job at the same time if the following conditions are met:

The college is supportive and doesn’t have strict rules against working while studying. Some colleges do not allow regular M.Tech students to take up jobs, so you must confirm with your department or faculty.

Your job is flexible and does not interfere with your classes, labs, or exams. M.Tech courses, especially in the first year, require time for lectures, assignments, and projects.

You manage your time well. Balancing both will be tough and may affect your performance if either becomes too demanding.

Your job is not full-time according to college rules. AICTE and UGC often expect regular M.Tech students to be fully engaged in academics. Some institutions may allow internships or part-time work but not full-time roles unless it's a part-time or evening M.Tech program.

So, if your college gives you written or official permission and your work timings are flexible, you can continue both. But always be careful that it does not break any university or AICTE rules, or you could face issues with your degree later.
