Do not USE,
This website will just collect your information and compile it into a pretty looking form. You still have to mail in all the supporting documents and a printed copy off the form your self. If you have a pdf editor you can do it all your self, or just go with the standard print and fill yourself method, your information is safer that way and you don't have to pay the unnecessary form fill fee.
AGAIN DO NOT USE this website waste of money for forms that are provided on government website for free.
I though I'd be doing my mom a favor by filling this online and having the agency submit the form for her. Now, both of us will have to risk our lives in this covid world by making an appointment with the immigration office to get forms sent and/or filled anyway. Kinda defeats the purpose of an "online application" as we believed it to be.
Here is my supporting evidence
