Visas & non-immigrant petitions
H-1B, L-1, O-1 and E-2 support packets: specialty-occupation memoranda, evidence indexes, RFE response research and exhibit tabbing built to your filing template.
Immigration Law support
Visas, green cards, asylum and removal defence — researched, chronologised and drafted to your filing standard. We work as a silent back office to immigration boutiques and the immigration desks of full-service firms, under your review and your signature.
What we cover
Green cards & adjustment of status
PERM and I-140 evidence assembly, I-485 checklists, priority-date tracking notes, and cross-checks between the petition narrative and the underlying record.
Asylum & humanitarian relief
Declaration drafting from client interviews, country-conditions research packets with sourced citations, corroboration matrices, and one-year-bar and nexus analysis.
Removal & deportation defence
Charging-document review, relief eligibility screens, cancellation and hardship evidence summaries, bond packets, and BIA brief research memoranda.
Naturalisation & citizenship
Good-moral-character review, continuous-residence timelines, prior-filing reconciliation and interview preparation memoranda.
Business & compliance immigration
Public-access file audits, wage-level research, corporate restructuring impact notes and onboarding compliance checklists.
