Got a Saudi opportunity

I am a 4.5 years experienced professional in the Cyber Identity domain, Got an offer from a saudi based cybersec company, as per the contract, they will send me to saudi for 3 months(on a business visa), after which i will return to india, and they will renew the visa(in next 10-20 days), and the process goes on...

My current salary is 10.8 here at deloitte, and including some benefits, it is around 12(+1 bonus at year end)

This new company is offering me 18 Lakh+ (didn't discuss the salary, but it is going to be in INR) They will give me 65 usd/day for the time I stay there Accomodation/stay, and flight expenses will be from the firm's end

I was looking for international exposure, but not specifically in gulf, sadly, i dont hold any other international offers. In the past, I had offers of 16 & 19 LPA in india. Were they better than the current one?
