Reconstruct lawful status and work authorization chronologically
Portability RFEs become much easier to answer when the officer can follow the beneficiary's H-1B history without guessing. Start with the prior approval notices, I-94 records, entry history, and payroll evidence, then arrange them around the filing date of the new petition. If the notice questions maintenance of status, explain who employed the beneficiary, whether wages were paid as required, and what status document covered each period. A clean timeline often matters more than volume because it prevents USCIS from inferring an unauthorized gap from disorganized records.
Address bridge petitions, gaps, and employer changes directly
Many H-1B transfer RFEs arise when there were multiple employer changes or overlapping filings before the current petition. The response should identify each prior filing, note whether it was approved, pending, withdrawn, or denied, and explain how that history affects portability eligibility. If there was a short unpaid period, a gap after termination, or a late-filed extension question, address it directly rather than hoping USCIS overlooks it. Bridge cases are most persuasive when the response explains exactly which petition and status document kept the beneficiary eligible at the moment of filing.
Separate portability eligibility from the merits of the new role
Even if portability is the headline issue, USCIS may still test whether the new petition describes a real specialty-occupation position supported by the employer's records. The response should therefore keep the two analyses distinct: first show why the beneficiary could lawfully port, then show why the new job, wage level, duties, and worksite arrangement support approval on the merits. Mixing those issues can leave both underexplained. A disciplined transfer response treats status and petition substance as separate burdens that both need to be met.
