One way ticket or Return ticket required?

[pradeepln]

My mom is coming this month to USA with tourist visa, she doesn't know English and I am planning to bring her along with my friend who is coming to USA. I don't have any plans for her return right now and I will plan her return trip along with some one who leaves USA during November or December. Since i don't know with whom she will be traveling back or in which airline she will be traveling back, I am thinking of booking a one way ticket for her.

Please let me know is there any law or is it mandatory to have a return ticket for people traveling in tourist visa during their immigration in USA?

Thanks
