Note: As kindly mentioned by Jan Doggen, this question is new, because I specifically talk about diffrence between business vs. tourist ESTA and how to obtain WB status.
I (german) applied for ESTA Dec 2015, it is valid until Dec 2017. I used it for a tourist trip in Dec 2015, and all information are according to that. I can only update the adress of my residence in the US.
I will go to the US again in May 2017 as visiting researcher for less than 90 days and hope to obtain Waiver Buisiness (WB) status uppon arrival.
Should I renew my ESTA to update all information (contact person, residence, travel reason, and so on) or should it also work with the current ESTA?
