here it is!A new law was amended recently(may be a year back).If u or anyone who has stayed in Qatar for 25 years or more, has proficient arabic knowledge and has not been in the court for crime r eligible for the qatar nationality.
Good news: U got just 3 more years inshallah
Bad news: ma frnd dad application rejected(around 26 years in qatar) coz he knew only to speak arabic but not write..so if ur not proficient..become b4 3 years.
