Bring accurate identity information, any existing immigration notices and the written classification assumptions in your proposal.
Ask for the basis, not a guess
Counsel should explain which current official information is relevant and what facts remain uncertain. Keep a dated copy of that advice with the underlying records. An estimate copied from an unrelated applicant or a broad programme advertisement cannot establish your own place in an immigration process.
Bring the material in a defined order and the consultation produces a usable record rather than a conversation. Identity documents for every proposed applicant come first, since nothing can be assessed without them. Existing immigration notices, petitions or refusals come second, because a prior filing can affect the present analysis in ways an applicant may not anticipate.
Any written proposal from a promoter or adviser comes third, with its classification assumptions marked so each can be tested individually rather than accepted as a package. Ask for the output in writing: the classification identified, the official information relied on, the date of the assessment and the points remaining uncertain. Keep that document with the underlying records.
An estimate copied from an unrelated applicant, or a figure drawn from general programme advertising, establishes nothing about an individual position. Ask finally which of those points would need rechecking before any payment is made, and record the date on which each was last confirmed.
