“Will you step into my parlor?” said the spider to the fly;

The guild of TAXLAWYER should win since 2009 - 5 consecutive Oscars for "corrupt" behaviour and liberal billing practices with regards to their offshore learning curve.
With regards to OVDI/P representation this guild/professional organization is guilty , in many, many cases of dishonest questionable practices, morally depraved, lacking integrity, debased in character , acting on mercenary financial motives without regard to honor,right or justice. Since 2009 this profession in the US had a windfall profit/jackpot of > $500mio. Amongst others - putting grandmothers on the government’s conveyor belt to oblivion.
Credibility must be earned. Most US tax lawyers have not earned credibility in this context .
After all the conversations/ e-mail exchanges I have had with tax lawyers over the last 5 years see below the habits that describes the trade the most accurate and reoccurred so many times :

1. does not really listen to you and your specific facts and circumstances – is basically on auto pilot
2. sometimes had the feeling you were speaking to a “stranger” because you received generic responses that have not much to do with your case
3. reading things into your statements that you have never said
4. makes remarks that constantly defends the IRS and the “system” as honorable and just
5. factual errors – small and bigger ones
6. disorganized with regards to billing statements and client correspondence 
7. they call it “research” any time they thought you were asking a really chargeable question
8. ”pro-actively” carry out unauthorized work and insist on charging you
9. hand-off your simple stuff to a different person every week to boost billable time and increase  mistakes because of no familiarity with the file
10. duplicate your own work to “verify” it and then charge you for the time
