Green card holder via marriage, decided after 10 years it's time to naturalize. Nothing exotic in the situation - still happily married, started a family, no legal issues, citizen of Western country etc. Is it worth retaining an immigration attorney for this? Most of my friends who have done this did it themselves and say it's a paper-filing exercise, simple test and an interview - so they think I'm being overly cautious to consider retaining counsel. What would be the considerations here, please? Thanks!
