You work directly with the attorney handling your case, not a rotating intake team. The caseload is deliberately limited so that the person who knows your file is the person standing up at the hearing.
That has a practical consequence worth knowing before you call: this practice does not take every case. If a matter needs a specialist elsewhere, or if the honest answer is that there is no relief available, you will hear it early rather than late.
Consultations are one-on-one. Bring whatever you have received from the immigration court or USCIS, even if it is incomplete.
