2026 immigration drafting software guide
Immigration drafting involves more than producing a first draft.
Attorneys need accurate case facts, supporting evidence, consistent petition letters, properly prepared forms, and a clear review process.
We compare five immigration AI platforms to help law firms choose software for petitions, RFE responses, legal briefs, support letters, and related preparation work.
Start with the work your team actually needs done. These are starting points based on advertised capabilities, not independently tested product rankings.
| Your main drafting need | Software to evaluate |
|---|---|
| Evidence-based petitions and RFEs | Drafty AI, Parley |
| Immigration legal research and drafting | VisaLaw AI |
| AI agents, case preparation and packet assembly | CaseBlink |
| Word-based drafting and agentic workflows | Parley |
| Firm-template letters within case preparation | Infinity |
| Forms, letters, evidence and existing CMS handoffs | Infinity, CaseBlink, Parley |
These are practical checks for AI immigration drafting software, including immigration petition drafting software, RFE response drafting software, and other immigration legal drafting tools.
A tool that drafts strong EB-1A petitions may not be the best fit for recurring H-1B or L-1 support letters.
Good drafting software should incorporate relevant information from documents rather than generate unsupported claims. An AI immigration letter generator still has to stay tied to the record.
Attorneys should be able to preserve preferred formats, argument structure, and document conventions.
Names, immigration history, employment details, dates, qualifications, and supporting facts must remain consistent.
Attorneys need to see what has been generated, verify case facts, correct errors, and approve the output.
Exhibit lists, evidence organization, and document references may matter as much as the letter.
Evaluate whether information must be copied into multiple tools or whether the drafting process connects with forms, documents, and existing systems.
The products overlap in their functionality. Some emphasize AI petition drafting and immigration evidence analysis. Others connect letters with forms and case preparation. This guide does not rank drafting accuracy, because it is not based on independent comparative testing.

| Case type | Drafting requirements | What to prioritize |
|---|---|---|
| H-1B | Employer support letter, consistent facts, applicable forms | Templates, forms, LCA consistency |
| L-1A/L-1B | Qualifying relationship, role, duties, supporting facts | Evidence extraction and structured letters |
| O-1A/O-1B | Evidence of achievements and applicable criteria | Evidence mapping and narrative drafting |
| EB-1A | Criteria-specific evidence and final merits arguments | Evidence analysis and legal drafting |
| EB-2 NIW | Proposed endeavor, qualifications, national-interest arguments | Structured drafting and research |
| RFE response | Government concerns, legal analysis, additional evidence | Issue mapping and cited responses |
| Marriage AOS | Relationship evidence, forms, supporting statements | Intake, forms, evidence consistency |
An O-1A petition may involve recommendation letters, awards, publications, professional memberships, media coverage, employment records, and other evidence.
The drafting process should begin with the actual evidence. Use the same approved file when you test O-1 petition drafting software.
Identify the relevant achievements, dates, organizations, roles, and other case facts.
Organize potentially relevant supporting records according to the attorney's legal strategy.
Use case-specific evidence to prepare the petition letter or legal brief.
Flag factual claims that lack sufficient support or require additional documentation.
Organize the supporting evidence and ensure references are consistent with the draft.
The attorney verifies the facts, evidence, legal framework, and final argument.
Ask vendors to demonstrate these steps using the same approved test evidence.
Compare the draft quality, unsupported claims, evidence references, and work required before attorney approval.
This is a recommended evaluation workflow, not a claim that all five platforms automate every step.
Consider an H-1B matter.
A drafting tool may help prepare the employer's support letter.
But the law firm may still need to:
Some platforms provide additional automation across these steps. The diagrams below are two ways to evaluate the work, not exclusive limits of any one product.
Infinity is designed to connect supported letter drafting with document extraction, forms, evidence preparation, DOL workflows, and CMS handoffs.
Measure how much work remains after generating the letter.
For some firms, a specialist drafting tool may be sufficient.
For others, connected case-preparation automation may be more valuable.
Public monthly or case prices below were checked against each vendor's pricing page. A lower starting price can cover a narrower slice of the work.

When evaluating cost, consider:
A good pilot uses one representative matter and evaluates actual output quality. Score each result yourself. This page does not pre-fill vendor scores or claim an independent benchmark.
| Evaluation criterion | What to check |
|---|---|
| Factual accuracy | Names, dates, roles and immigration history |
| Evidence support | Whether claims are backed by supplied records |
| Legal reasoning | Appropriate arguments and accurate authorities |
| Template adherence | Whether the firm's structure is followed |
| Completeness | Relevant facts, required sections and attachments |
| Consistency | Agreement between documents, forms and letters |
| Editing effort | Changes needed before attorney approval |
| Review transparency | Ability to inspect and verify the output |
| Workflow fit | How the output moves into existing processes |
Use a simple 1–5 score for each criterion based on your team's own observations.
Record any unsupported factual claims, incorrect evidence references, and missing sections separately.
Match the product to the drafting work that consumes your team, then measure what is still left before an attorney can approve the file.
Your main challenge is preparing complex petitions, RFEs, expert letters, or other evidence-heavy legal writing.
Legal research, immigration law analysis, and drafting are closely connected in your work.
Your team wants AI-assisted drafting together with forms, evidence workflows, and Word-based editing.
You want an immigration-specific workspace/system of record with agentic case preparation and per-seat pricing.
Your team wants firm-template letters, supported forms, evidence preparation, and intake steps connected within an automated workflow around an existing CMS.
Choose based on your actual case mix and the amount of work left after generating an initial draft.
The best software is the one that produces reliable, reviewable work while fitting your firm's existing process and budget.
There is no universal winner. Drafty, VisaLaw, Parley, CaseBlink, and Infinity serve overlapping but different drafting and preparation requirements.
Yes. Several immigration-specific platforms draft petitions and supporting letters using case information and evidence. Attorneys must review the output.
Drafty, VisaLaw, and Parley advertise capabilities relevant to RFE drafting. Verify exact case-type and workflow support before purchasing.
Immigration AI tools can help analyze evidence and prepare drafts for these case types, but the final legal arguments and eligibility analysis require attorney oversight.
Reliability depends on input evidence, case complexity, software capabilities, and review procedures. AI output must be checked for unsupported facts, incorrect legal citations, and omissions.
Several platforms support custom templates or drafting instructions. Infinity supports firm-specific letter templates within configured workflows.
Some products also offer form preparation. This varies by vendor, plan, and case category.
Public prices range from per-seat subscriptions to matter allowances, AI credits, and case-based pricing. Compare the included work, not simply the starting price.
No. Attorneys remain responsible for legal strategy, legal judgment, verification, and final filing decisions.
Test factual accuracy, evidence references, legal reasoning, template consistency, completeness, correction effort, and integration with current workflows.
If your firm's biggest bottleneck is repetitive immigration case preparation, drafting is only part of the opportunity.
Infinity helps prepare supported forms, firm-template letters, evidence, and related case materials for attorney review.
Show us your current process and a representative case type. We'll demonstrate what Infinity can automate and which steps stay with your team.
