so sorry to heard your situation.
do you have any other relatives live near you?
you said your patent have a shop in USA, how can they manager it without persent?
you can tell them try the short term businese visa to come back to new york and bring the documents to show they own business in US. tell them make sure to let the embassy officer know they will not stay in USA because they also own business in HK.
if they reject them, then ask for either 1 person visa, another one will stay in HK. this might let the officer believe they will come back to HK.
try to avoid mention about you are stay in USA alone. that is violation in US law that parent left a 12 years old child behind.
