H4 Extension(i-539) e-Filing - Signature Field Assistance

[Jaggu0420]

Hi, I am in the process of e-filing (i.e. Online) my wife’s H4 – Extension (i-539 form) and I am all good with the details on the application form however I need a little assistance /advise from you here.

I filled all the details on i-539 form and just about to proceed to payment option – I see a Signature field (like shown below). I am confused seeing the Signature field for an online form and not sure how to sign it as it’s online form.

Should I just key in my wife’s full name in signature field or should I use DocuSign or some other tools to incorporate her esignature. Could you advise?

Must have someone had experienced this, please advise & assist.

Thanks in advance!
