Uninterrupted Cognitive Development
Families of English language learners generally have a high rate of mobility. Relocation is hard for any child, but relocating to a new country where a new language is spoken is especially difficult. While the family is struggling to adapt to new laws and culture, the children frequently have sporadic attendance in school. In many cases, these children had poor or interrupted education before they even emigrated to the new country. Needless to say, this all has a very negative impact on the child's cogitive development.
