In case you need, ACM can provide a standard letter to support your VISA application and describing the conference and your relation to it (e.g. author, travel grant recipient, etc.). Please contact Stephanie Smith at ACM (smith_s at hq.acm.org) to request such a letter to be written for you - do not ask the General Chair or the various Chairs to write supporting documentation because they cannot do that for you.
Please understand that the above is all we can do to support your visa application, and whether the letter from ACM is sufficient or not to get you a VISA is not under our control.
Also note that the 'invitation letter' such as the one suggested as an alternative to the proof of lodging is not something we can write for you as it involves legal and economic liability of the signer of the letter.
