Nightlight maybe used to be a good agency - but they are not anymore. Specifically the International Adoption Program for Haiti - based in Loveland Colorado.
Countless mistakes (paperwork, poorly translated documents, outdated forms) were made from their end delaying adoptions for months and months. They communicate infrequently and are also defensive and aggressive if you question the process at all. When faced with owning up to their errors they will blame you for "not understanding the paperwork". They also ignored a complaint from a parent of an abuse scandal at an orphanage (suspected in 2015) till 2017 when they were forced to face the issue when 5 confirmed cases of the abuse came to light after testing was done on one of of the children home in the US.
If I could give zero stars I would. Our experience was awful.
