Do not invent a general L-1B recruitment test. The actual knowledge and other category conditions require evidence.
Use the correct standard
Recruiting expenses do not substitute for qualifying knowledge or foreign employment.
Filing fees published in the USCIS fee schedule, professional fees reflecting the evidence work, and internal quality and operations time to extract and organize the records that support the knowledge claim. Clarify whether the professional engagement includes reviewing confidential evidence, offsite work arrangements, or responding to later government questions, and confirm current filing fees for this specific employer. Professional fees for L-1B often run higher than for a comparable L-1A because the specialized-knowledge evidence takes more work to assemble and the offsite-placement issue needs a careful contract review. Build a dated review file around the specialized-knowledge record, training invoices, payroll, worksite evidence, and current government-charge information. Make a budget that separates filing charges, optional processing costs, translations, technical-document preparation, travel, and the employer's ordinary project expenses. Budget the shared and individual portions separately, since the corporate evidence is prepared once while interviews, evidence gathering, and drafting a distinct knowledge account do not compress with numbers.
