Please refer to this previous question of mine:

As someone with low grades how can I prepare myself to study MSc in CS in USA?

Would it be a good idea to quit my job to prepare for the GRE and TOEFL?

I live in Bangladesh. With a background in IT, I am doing a job in a bank. I am 32. Honestly speaking I am done with my job. With an ambition to do a PhD from a USA/Canadian/German university, I have understood that my current job is actually going to get me nowhere.

Some answerers of the previous questions pointed out the importance of having a job in the related discipline, proving research capability, involving in research activity, being a part of a research group and so on.

After considering all these points, I am actually strongly planning to quit my job and get enrolled in a "Masters with thesis" program in CSE in a local university. My previous degree was in Information Technology which is, I guess, considered a professional discipline. So, I am going for a CSE degree. As far as I know, Information Technology degree is not considered a fundamental discipline.

My plan is this: (1) I shall complete a masters degree in CSE with a thesis, (2) write and publish one/two research articles and finally (3) complete GRE+TOEFL, if required.

And one more thing, I want to secure a funding either in the form of Assistant, Teaching Assistant(TA), Research Assistant, Research Fellow or anything else.

Please tell me about my prospect as a Masters-by-thesis candidate along with a funding after completing this series of actions.

Is the risk of quitting the job worth taken?
