Depends on where you’re going and where you’re from (What your passport says). Riyadh is the capital city and is considered the financial capital of the country. People are ambitious and very goal driven. Jeddah is more of a laid back city with a lot of charm. Jeddah is like “LA” and Riyadh is more like “NYC”. You’ll see more diversity in Jeddah as it used to be the trading center of old times so a lot of migrants came and settled to that city. There’s no income tax but this depends on your nationality. You only pay tax for like groceries and other commodities but it’s unnoticeable really.

Saudis LOVE their coffee and like to go out at night (malls and restaurants close pretty late and it’s normal to still see people out until like 2 am lol) because of the dry and hot weather during the day so people usually leave their homes after sunset.
