## Supported forms

Lexfill currently supports thirteen USCIS forms, plus two litigation intake questionnaires (below):

**Green cards & family**

| Form      | Purpose                                                                    |

| --------- | ------------------------------ |
| **N-400** | Application for Naturalization |

**Humanitarian**

| Form      | Purpose                                                                    |
| --------- | -------------------------------------------------------------------------- |
| **I-589** | Application for Asylum and for Withholding of Removal (affirmative filing) |

**Attorney-side filing forms**

| Form      | Purpose                                   |
| --------- | ----------------------------------------- |
| **G-28**  | Notice of Entry of Appearance as Attorney |
| **I-907** | Request for Premium Processing Service    |

Two of the thirteen — **G-28 and I-907 — are attorney-only**: clients are never asked a single question on them. They arrive pre-filled from your firm, attorney, and client records, stay editable field-by-field by the legal team, and are included automatically in assembled filing packets for the case types that need them. Clients fill the other eleven.

More forms are added regularly — the intake engine, PDF filling, and translations are all form-agnostic, so new forms plug into the same experience.

## Litigation intakes

The two **litigation** case types use a different kind of form: an intake questionnaire. Nothing on either is filed with USCIS — each collects the facts a federal court filing is built from, and the outputs are court documents rather than a filled USCIS form.

### Federal Mandamus

The **mandamus intake questionnaire** collects the facts a federal unreasonable-delay lawsuit is built from:

* **The delayed application** — receipt number, filing date, the office handling the case, and the current status.
* **Case timeline** — every notice, appointment, and response, in order.
* **Attempts to resolve the delay** — e-Requests, USCIS calls, Ombudsman and congressional inquiries, expedite requests.
* **Hardship** — the specific, personal consequences of the delay.

Risk screening and venue/counsel live on the **attorney worksheet** — the client never sees them. The outputs: a delay analysis graded against USCIS's own published processing times, a drafted federal complaint, and the complete filing package (JS-44 civil cover sheet, AO 440 summonses, and the service documents).

### Habeas Corpus – Detention (28 U.S.C. § 2241)

The **habeas intake questionnaire** collects the facts a federal detention-review petition is built from. Because the client is detained, it is written to be completed by the attorney, their staff, or a family member:

* **Where they are held** — the facility and its street address, the A-number, and every period in immigration custody (which drives both the venue and the time-detained math).
* **The immigration case** — the case's posture (proceedings pending, final removal order, and related history), appeal status, and travel-document history.
* **Bond requests** — each bond request, the judge's decision and its stated ground, and any appeal.
* **Health, family & who is filling this out** — medical needs, family circumstances, conditions at the facility, and who is completing the form on the detained person's behalf.

Claims screening and venue/respondents live on the **attorney worksheet** — the family never sees them. The outputs: a detention analysis with its reasons spelled out, a drafted § 2241 habeas petition with its verification block, and the complete filing package (JS-44 civil cover sheet with the Alien Detainee nature-of-suit, AO 440 summonses per respondent, the service documents, and — when requested on the worksheet — an application for an order to show cause, which asks the court to set a fast response deadline).

## Case-type pathways

Questions can be scoped to a case type. When you start an intake you choose the case type, and the client only sees the questions relevant to their pathway — no dead-end or inapplicable questions.

Questions are also split by audience:

* **Client questionnaire** — what the client answers during intake.
* **Attorney worksheet** — system and legal-strategy questions reserved for the attorney, never shown to clients.

## The Forms tab

On a client's profile, the **Forms** tab shows each form as a fillable preview, organized into the attorney worksheet and the client questionnaire. You can:

* See every question with its prompt, helper text, and current answer.
* Edit answers directly — including ones the client hasn't reached yet.
* Catch implausible values early (for example, date sanity checks).

## Cross-form reuse

Answers are harvested into a single per-client profile. When a client starts a second form, fields the firm already has are filled automatically — Lexfill only ever fills empty fields, never overwriting existing answers.
