Hey Iowa Girl!!
I have been 3 years in UAE and this is my second in Qatar.
You can tell your parents that Qatar is a very safe place with people from all oer the world.
Beeing an expat requires adjustments to culture and I am sure the girls would let u know about it mainly for Public Places.
Be nice, Be you, Be open, Be friendly and Kepp your eyes open!!
good luck
I will show you around if we will work for the same company.:)
