@rolex123, as of my knowledge, i-134 is a pdf file format (which actually allows text insertion to add informations). The host can fill the informations either using pen on the raw print out form or insert the informations on computer, then print the filled form. The form then should be signed using
pen, and sent through postal service (or...scan through signed form and send it through email) directly to the applicant who is going to submit it at the time of interview, if asked. I don't think it is possible to use electronic signature.
The second thing, i couldn't figure out why the host goes to nearest USCIS office where he lives. I think the form doesn't need confirmation form any office in US.
I'm really willing to accept if there is any correction.
