From what you have written, let me tell you one bitter truth. You have very poor English communication and writing skills. This means that you will not be eligible for the jobs abroad due to the absence of this basic knowledge they look for in a foreigner candidate. When you apply for a job abroad, then they will first screen your application and check whether your qualification and other details given in the resume meet the criteria preset by the company.
If you pass in that screening, then you will be selected for an initial telephonic interview. They might also conduct a video conference interview, and might want to see how good are you in English communication skills. You won't be able to clear the screening level. So, first and foremost to clear the first round of screening, please enroll in a one year diploma course on communication skills. You are a final year student. This course will help you a lot in securing good job.
Regarding civil engineering jobs abroad , Dubai and Singapore are the best places. Next best country is Qatar. All these countries offer high paying jobs. Only thing is that in all these 3 countries residential costs are pretty high. You will have to stay in a rented flat in such locations. Rent are pretty high in these countries and almost half your salary will go in it.
The job positions available at such locations will be engineer trainees, quantity surveyors, maintenance engineers, mechanical draughtsman, etc. So work hard and you will definitely succeed there.
