Per RapidVisa's instructions:
The U.S. citizen sponsor must print, sign, and mail this form, along with photocopies of the required supporting documents, to the beneficiary 30–90 days before the interview date. The sponsor’s original signature is required –– the U.S. Embassy will not accept a scanned or faxed signature.
When I wanted this clarified whether or not I have to FedEx sensitive (tax etc.) documents from here to Philippines, RapidVisa said:
I understand your concerns about mailing sensitive documents. In situations like this, sponsors are permitted to electronically send scanned copies of the original documents. For the signature page of the Form I-864, it is necessary for the sponsor to sign it with a wet signature, preferably using a black pen. After signing, you can scan the document and send it to the beneficiary so that she can have it prepared before the visa interview.
So, there are contradictions and wondering if any of y'all have FedExed your affidavit of support documents to Philippines or merely scanned, emailed. Also, RapidVisa said to send them "...30-90 days before the embassy appointment." Is there a timeframe on this, as well? Thoughts??
