Hey!

I would really recommend you to go for the option you want personally rather than choosing  for the sake of someone or if someone is forcing you to do.

Both the options cant be compared with each other as both are different streams having different values . Think what you want to do, where you want to see after 10 years, which occupation will give you happiness and wealth.

If you go abroad, You will settle down working in a mnc with a reputed position and wealth or having a company of your own. In UPSC, after clearing you will be IAS of your area. You will have power, wealth ,respect which is incomparable .(UPSC is one of the toughest exam in India)

Again I would say , do what you want in your life.

Hope it helps! All the best!
