Yes, you can definitely join XLRI if you are selected for the course. However, there will be some dues you might have to pay at your previous university before you come for XLRI. If you do that, then there will be no issue, whatsoever.

Hi Ethan,
Normally, they do accept Diploma for entry into Bachelor's degree courses. You will find the requirements on college websites, it is difficult to mention names since there are so many. You must take the IELTS also.

I will prefer you to go for MS but in USA because after completion of your MS in UK, you will not be able to get a work visa there. So, you will not be allowed to do the job there. It takes lots of paper work if you want to.

Admission is based on marks obtained in 10+2. Interested candidates can apply online/ offline with required information.
Please check for your Eligibility to apply for this course from the criteria mentioned below:
Candidate must be a graduate in any discipline from a recognized university.
Note: students who have completed 10+2 or graduation through Open University with no prior qualification in prosecuting are not eligible to apply.
Regards.

Dear Sreeram,
There is no change as of yet. Rules are strict and rigid. You may want to check the immigration UK website directly for updates and details.

Hi, Kindly contact the university authorities.

UK is always better than Singapore. Fees required for Singapore is less as compared to UK.

Hi,
You just have to start researching and learning about university admission requirements. 20 attempts and 8 backlogs is a big number, considering your final CGPA is also not very high admissions in top rated universities will be a challenge. You can search for programmes in UK, Poland, Ireland, Italy, Spain, Australia, Malaysia, etc. Expand your search and explore. For any doubts never hesitate to email the universities. Work on your personal statement, a very good SOP can work wonders. Recommendation letters are also a huge impact factor. IELTS or TOEFL score, GRE also matters. Keep searching.

Yes, of course, it is a better option for that. You can also look for New Zealand, Canada, Australia, etc.
