Past expenditure does not establish the current facts. Identify which records remain accurate and which parts of the new arrangement require assessment.
Reuse evidence only where it still describes reality
Separate current government charges and genuine document needs from previous costs. A desire to avoid repeating work cannot justify using an obsolete employer or duty description.
Beyond legal review and any credential evaluation or translation, budget for documenting multiple work locations, and check separately whether a state licence or registration for geology practice carries its own application costs. Refer to the USCIS fee schedule for the current amounts rather than an older quotation; the I-129 fee and any premium-processing fee apply only if the employer petitions from inside the United States, and the port-of-entry route uses a different, lower charge. Having the employer file Form I-129 with USCIS in advance involves the petition fee in the current fee schedule and, if speed matters, the optional premium-processing fee; the applicant then presents the approval notice at the border. The expense nobody plans for is the second attempt: a refusal recorded because a letter leaned on experience for a degree-only profession is answered for in every later application, and reopening it costs far more than the first review would have.
