mine was under EMPLOYMENT HISTORY,
After 9 days since I submitted my online application, I was browsing my student visa files and I noticed I put "Philippines" on my employer's address, instead of Saudi Arabia!
I am so down right now... I worked hard on this app (DIY), I checked all my details multiple times BUT THEN I still committed error.
The thing is, I filled and printed my form initially on October 31, I noticed I committed the same error as above and corrected it. Fast forward to Nov. 8, I changed my form since I want to update the date and funds available for my stay, I cleared the form then fill it all over again, little did I know that I keep on committing the same mistake with the address of my employers!
(Probably because almost all the address I have filled was my province/country, like education, address of parents/siblings etc.
I attached under Client Information my Employment Certificate from my current Employer (there was a complete address on the letterhead), I have bank statement with payroll deposits and even payslips attached under Proof of Means of Financial Support which proves that my employer was indeed located in Saudi Arabia.
I hope this is also a "minor mistake" and will be considered by the VO.
