My cousin wants to send her 16 year old daughter to visit my family for 3 weeks this summer. This will require her to fly from her home in Russia to my home in the USA alone. She speaks some English.
I am a US citizen and I have arranged visas for a number of my family members to visit in the past, so I am familiar with the general visa process. I am having a hard time finding specific information on the requirements and potential complications for an unaccompanied minor. I found this article from US Customs and Border Patrol, but it is very vague and links to the Department of State website, where I could find no further information.
I'm interested in any requirements or complications that might arise from her being an unaccompanied minor: how this will affect the visa process, any requirements that the airlines impose, and any other potential hazards or complications. I am especially interested in official written guidelines, but I would also appreciate advice from anyone who has done this.
