Visitor Visa - B2

I would like to marry an a american citizen for mutual benefits. Anyone who wish to help.

Pls msg me and we can discuss more.

I had my interview today in Dhahran consulate. Went like this:

VO: Purpose of trip?
ME:Tourism and meeting a friend

VO: First time going to the states?
ME: Yes

VO:How Long you have been in Saudi Arabia (I'm not sure if the question was since when...i forgot)
ME:Since 14-sept-2014

VO: Which Company do you work for:
ME: Told ( some words were abbreviated , for example i said Br. instead of branch, Co instead of company)

VO:What do you do for the company
ME: Mechanical engineer (i thought she meant position, maybe she meant what was y role, i probably should have asked her to elaborate)

VO:Monthly Salary?
ME:10024 SAR per month

VO:Who will pay for your trip
ME: I will

VO: did you visit an country for the purpose of tourism before?
ME: Bahrain and Turkey (I Probably shouldn't have mentioned Turkey since i stayed there for 2 months for an internship even though i did some tourism during that time)

VO rolled her eyes then as asked: Do you have family in Saudi arabia?
ME: No Family in Saudi arabia

VO asked to put my left hand fingers for fingerprint then typed on the PC for 15 seconds and told me I'm currently not qualified.

I thought i had good credentials given my following profile:

Male, Lebanese ,24 Years old

Graduated from the American University of Beirut (Top second university in the middle east)

Mechanical engineer working for a huge contractor whose client is ARAMCO

Monthly Salary : 10024 SAR per month + annual bonus

Company provides food, accommodation, transportation and 3 round trip tickets per year

Money in Saudi Bank : 25000 SAR

Money in Lebanese Bank : 31500 $ (Money i earned from this job and transferred to Lebanon)

Moreover, i indicated in my application the days that i will be in the (6 Days) + the hotel i will staying in+ the places i will visit

NO DOCUMENTS WERE ASKED, i had a good letter form the employer stating the leave days and requesting from the consulate to give me the appropriate visa and that I'm going to the US for tourism purpose. I had my bank accounts certificates, hotel reservation, University certificate etc. but none were asked for.

Conclusion:

Right when i went to the counter, the VO was telling her coworker that today she has a 54% rejection and she seemed really happy about it . Anyways, i don't know what went wrong, iam not sure if i should have explained my self more, for example telling that all my family is close by in lebanon... i mean after reading a lot of cases i thought that its better to answer to the point, but it looks like that didn't work for me. Also probably i should have offered her the certificate of employment right after she asked whom do i work for as i had strong letter, or should her my bank statements when i said that I will pay for my trip

Rejection really sucks and i sympathize with anyone who went through this.

Appreciate any comment that will further show were i also did mistake, and i hope that people will learn from my case
