Remove "country" choice from address quick tool

I would like my form not to have the option of "County". I want to make it only fillable by people in the USA. Is there a way to do that? I seem to get many junk auto fills by robots from Russia, even with Captcha installed.

You can remove the field(s) you don't want to use on the Address quick tool by clicking on the Fields button and unchecking them.

However, from what I understand you want to prevent users from other countries to access your form. If that's the case removing that field will not prevent this from happening since this has to be done on the server(s) that are rendering your site. You can read more about it here: http://www.inmotionhosting.com/support/website/htaccess/block-country-ips

You may also try to add a Google reCaptcha widget in your form to see if it provides better results that your current captcha field.

Hope this helps.

If you require further assistance, please let us know.
Thanks.

Thank you!
