Salam Alykum
Oh eayh public eduationa is free, see bro, if a certain school didnt accept a forign kid its not because they stopped accepting non-saudies but because there are no available seats.
I am in indian, I was born in Saudi, Dammam more specificlly, I lived here untill I was 18, then went to malaysia and lived there for 5 years, came back and got married, my husband works in damma so we are still in Saudi.
I agree with sister Mercedes in everything she said. Its a safe country, am I saying 100% safe?, of course not, but it has low crime rate compared to other countires. I cant count the times I used the taxis and thanks Allah so far nothin happend. I go to resturents alone to meet my freinds and never once policeman stopped me asking for a mahram. I also travelled to Malaysia alone and never been questioned.
There are lots of Dawah centers in every city, they are DESPERET to get some volunteers for dawah work, unfortunatly, peaple prefer to stay home and complain that there is nothing to in saudi.
The peaple here (not the goverment) are SO nice, I lived among them and they treated me as like one of them, they have their own short comings, yet, they are so unique. Rents are considered the cheapest compared to other gulf countires, overall one can do lots of saving living here and thats why THOUSANDS of non-saudis live here. Life here is much cheaper than life in the UK.
Muslims environment is great, yes there are some peaple who drink and commit adultary, even at Prophets time there were muslims who used to drink despite the prohibition, but its not done in public.
