Invisalign Treatment - Transferring from UK to US, how do I go about this?

I have paid off everything to my UK dentist for invisalign and have requested that I get it fitted when I travel back next month. Will a US dentist will assist with any follow up work needed with regards to invisalign given that it was done by another dentist? Should I have my UK dentist transfer all of the information and products and have a US dentist fit it? Thanks
