Ironic this thread was bumped today. I submitted a KSA Business Visa application today, and I filled the application three times.
First time I answered how I answer at my doctor's office and at the hospital: Jedi. My office's travel guy who reviewed the app objected, so I filled out another one.
Second time i answered how I answer when someone pushes me: Atheist. The travel guy objected again.
Finally I said f!!! it, and I answered Christian-Roman Catholic. i was baptized and received my first communion, but was never confirmed, so I sort of count. He accepted this one.
Hopefully the embassy is ok with this.
