Hi All, Recently few of us (my friends) were discussing on the topic of sponsoring in laws when they visit us abroad. Its definitely fine to sponsor for our parents whether they are wife's or husbands's parents. But what would you do if your married sister in law wants to accompany her parents along with her kid? Do you sponsor her's and her kid's air fare as well? Anyways you will have to cover her local site seeing or trip costs but how about air fare? Would like to know your take on this.
