My husband came to the US illegally at the age of 11. We have been married for a little less than a year and are finding it difficult to live with his situation. He does not have a visa or an ITIN # yet. We would like to start the naturalization process as soon as possible. Questions are: How much does it cost (average), how long will it take (average), will he have to leave the country? Do you have any recommendations of lawyers in the DFW area?
