Our son wasn't as old as your daughter but was 4 1/2 when he came home. He had not had any of the typical preschool experiences. He had no knowledge of colors, numbers, shapes, etc...even in Spanish. He will be home 2 years in April and is kindergarten right now. Still at the beginning of this school year letters did not make any sense at all. Right now he knows all of his letters and is starting to read a few sight words. So in the past 2 - 3 months has really caught up.

I have done quite a bit of research and reading on this and it seems that most experts say expect 3 - 5 years to be academically fluent which is a lot different than conversationally fluent. Basically within about 4 or 5 months he was speaking a lot of English. He started preschool 5 afternoons a week in Sept after he came home in April and everyone could understand him.

With your daughter being a little older and no prior education it will probably be a little more difficult since her same aged peers won't be learning letters, numbers, etc where as Isaac, even though somewhat behind the other kids, still was able to learn these with his peers.

Yes I think you will probably need to be able to spend more time with her and I would also start right researching schools, educators, etc. in your area and coming up with a plan as to what her education is going to look like. I am also an educator(have taught kindergarten - 2nd grade) and know that not all schools, teachers, etc. have programs that will work for your daughter.
