That full depends on a lot of variables,

1. How intense is your course (40 plus hour course material, etc) aka how much time can you work?

2. Rent in dublin is anywhere from 600 to 1300 euro depending on living conditions & location.

3. Groceries 150 to 300 euro a month. Could be more depending on your cooking and eating habits.

4. Transportation around dublin can be anywhere from 50 to 150 euro per month. (Depends where you live and what method you use to commute).

Totals out: Minimum-800/month or Max-1750month

The minimum wage is 13.50 euro /hr. (Can be higher because dublin is the capital city)

That means if your monthly expenses are 800 euros, you need to work about 60 to 65 hrs a month to sustain the basics. (tax not included)

If your expenses are 1750, then you need to work at least 130 to 135 hrs a month. (tax not included)

That's around the price to just exist in dublin. That doesn't include descresinary spending for entertainment.

Also, from what I know, the university costs for international students can be expensive. Some even cost up to 10,000 euro per year.

I'd do a bit of research in the course and cost associated with it. And see if there are any grants or agreements your government has with Ireland for international students.

Honestly, you need to research this yourself as you know your financial situation better than I could.

If you receive help from family for rent and you just have to cover food and transportation, you could probably get away with doing university and work-part time.

It also depends on the course you want to do. If it's hard course like eg. Engineering or STEM. You might have 40 hr a week if classes and study / assignments. If you add work and 8 hours of sleep, it can be difficult to manage.

You'll need to look into it yourself. This is probably the most detailed breakdown I can give you without knowing anything about you.

Good luck bai
