Hi Shubham,
An overall score of 6.5 with no module less than 6 is typically required for admissions into PG courses. You may further check college specific requirements on college websites.

Since you are an international student, you are going to have to pay out of state tuition rates for whichever school you attend. So, your tuition is going to be high. For engineering/business that means, your tuition will be in the ballpark of $35,000 per year. Your yearly cost of doing a Masters would be around $40,000, which includes your accommodation, tuition, and other expenses related to the course.
Regards.

Most of the German and Canadian Universities require minimum of 6.5/9 in IELTS and sometimes even minimum of 6 in each section
Try to score at least 7/9 in IELTS and it's not that tough to score.
Regards.

Hi Mohitha,
Both are widely accepted but I will first ask you where you want to study, certain countries have their preferences.

Hi,
USA and Singapore for some of the best architectural programs and skills. You can also consider Germany, Japan, China, Hong Kong, Netherlands, Italy, Canada etc. You have to choose basis your budget etc. You have to see if your profile meets the admission requirements or not. Go through university websites in specific countries, check the requirements, fees etc. and choose.

Hi Surya, you may try applying under SPP colleges for PG Diploma courses. For MS programs and non SPP, admission chances for you are very less and even if you get through a college there is a chance of visa rejection. Try contacting some colleges yourself before applying.

Hi Nandagopan, IELTS academic is taken for studying abroad but for jobs you must take IELTS general. But if you study abroad and apply for work permit or get a job after studies you don't have to give the IELTS again. But if you apply for PR you may have to take the IELTS again depending on the country's policy. You can talk with visa or immigration agent and clear out your doubt.

Hi Yatin, it will be difficult to say which countries you can go, you have to randomly contact universities worldwide, get in touch with university agents or representatives, attend education fairs, email the universities and find out. Some universities may accept NIOS, some may not. See USA, Canada, Australia, New Zealand, Netherlands, France etc.
