For question in DS-160, Person/Entity paying for your trip -
Friends Mother is elderly widow who has visited USA multiple times since 2006 and already has US visa stamped twice in the past. She is applying drop box now.
Her son is US citizen and he would like to pay for her trip. So she will answer Person/Entity paying for your trip - Other person, relationship to you - child?
Will this cause any issues with Dropbox or getting called for an interview?
