Make sure you do the consultation with them before signing any documents. They charged $575 for a simple tax return. FYI, all they did was prepare the form. Wanted them to see if I qualify for the foreign earned income tax but they didnt know that since they didnt do a consultation until AFTER they prepared the regular tax return. Save yourself $545 and do your taxes online. Legal scam artists.
