Don't worry about it and just complete it asap. They can ask you for whatever they want, how often they want, whenever they want. There is no need to worry so long as all your information is accurate and you haven't omitted anything.
Thank you very much for the reply,
I was super nervous here is what I did.
Me and my spouse filled separate forms. My spouse once got US visitor visa rejection but he got 10 year US visitor visa on the second application. So he mentioned that on the form. By replying statutory question 6-D as YES with explanation. But When I filled my question I answered the exact question as NO since I have never received any rejection. I did not pay attention to the question since it is saying...'any of your family members listed...' so my answer was also supposed to be YES
I have realized it after I uploading it to My GCKey. However after realizing it (next day) I have immediately filled a webform explaining that mistake and uploaded correct form there. I am not sure if the officer will realize the web form or legally if this will be considered as misrepresentation? I am super depressed for this mistake any idea what else I can do to fix it.
Thank you
