I am inviting my friend to visit US and do I need to provide I-134 form (affidavet of support) for them to get visa?
-Yes if you will provide the financial support for their travel.
My friends' daughter is about 15 years old, do I need to file a separate I-134 form for her if required?
-No. Juts list all the people you will support in the I-134.
