Lengthy process? Not really. If you exclude the five year waiting period.
Costly? No, not really. The application fee was minimal. There was a no brainier test.
Altogether, the process was simple and inexpensive.
Now if ine has to take classes to learn the language, that might cost some bucks .
So, according to you, ten years, four tries, and thousands of dollars in lawyer fees to become a legal citizen is inconsequential? Plus, you had to find a Vietnamese friend to hand you a copy of the questions and answers on the verbal test.
I know someone who was born to an unwed mother who came across the border on a "green card", one for the mother and one for the child. Mother remarried but the stepdad did not officially adopt so there was no citizenship there.
Even though this person's only memories were entirely of this nation from three years old and neither knew of nor owed any allegiance to the country he was born in but only the US, that genrated no support when the attempt was made to attain citizenship.
So glad you believe that is no trouble at all then. (/sarc)
