I have been accepted as a student of MSc in big data analytics for business. I have a 3 year bachelor degree.

I means AM I ELIGIBLE FOR APS?

Dear Ashwani, it will depend on the type of your student visa that you receive in your home country. If you have a visa "ceseda", you can renew it in France 3 months before the expiration date.

You can only apply for APS after you graduate.

The same type of visa is eligible for an APS once you get your diploma.

You will do your studies with a student visa, then a residence student residence permit.
at the end of your studies, applying for APS enables you to look for a full time position in France

I’ll have a 270 ECTS after completion of this diploma. I AM eligible for APS right?

All MScs are recognised by the Ministry and thus eligible for APS at the end of your studies.

The APS can get me a residence permit for how many months?

One year, renewable once.

So i will have 2 years to find a job?

And i can apply for the APS if i am Lebanese?

Yes, you can apply whatever your nationality, but sometimes APS cannot be renewed. you will have to check it with prefecture after you graduate.
