🟢check_form_edition(form)
Returns the edition of one USCIS form that USCIS accepts today, with its accept-from and reject-from dates. Use it to confirm a filer has the right form version before filing. If USCIS has announced a newer edition it does not accept yet, announced_edition gives that edition and its accept-from date. For edition changes across all forms since a date, use list_form_changes. Covers I-90, I-129, I-130, I-131, I-140, I-485, I-539, I-765, and N-400; any other form returns not_found. Free, no sign-in required. Limit: 20 calls per minute per IP, then rate_limited. Not legal advice. Source: the form's page on uscis.gov, or a dated web.archive.org capture of that page.

}🟢list_form_changes(since)
Lists every form edition change and every USCIS or Federal Register alert published on or after a date, newest first. Use it to catch up on what changed since a last check. For one form's current edition, use check_form_edition. To find alerts by keyword, use search_alerts. Returns all matches in one response with no paging; empty lists mean nothing changed. Free, no sign-in required. Limit: 20 calls per minute per IP, then rate_limited. Not legal advice. Sources: uscis.gov form pages or dated web.archive.org captures of them, USCIS newsroom alerts, and Federal Register notices. The top-level source URL identifies the exact aggregate query. Each alert and form change keeps its own source URL and content hash.

}🟢get_fee(form, filing, category)
Returns the general filing fee for a USCIS form and filing method, in US cents, with the date it took effect. Use it when the user asks what a form costs to file. Only the general fee is on file: category-specific fees are unavailable, so omit category. Covers I-90, I-130, I-140, I-485, I-539, I-765, and N-400, paper and online; any other form returns not_found. For the form's current edition, use check_form_edition. Requires sign-in at https://immigrationlayer.com/login and an active plan. Without a plan it returns subscription_required. Limit: 30 calls per minute per account, shared by all paid tools, then rate_limited. Not legal advice. Sources: the USCIS fee schedule (Form G-1055) and the 2024 USCIS fee rule (89 FR 6194).

}🟢get_processing_time(form, category, office)
Returns the USCIS processing-time estimate for one form, eligibility category, and office: the time within which 80% of cases were completed, in months, weeks, or days. Use it when the user asks how long USCIS takes to decide a form. Pass form, category, and office exactly as the USCIS processing times tool lists them. Every estimate on file has both a category and an office, so omitting either returns not_found. For Visa Bulletin waits, use get_visa_bulletin.

Returns the Diversity Visa (DV lottery) rank cutoff for one region in a month's Visa Bulletin, or a country exception the bulletin lists within that region.

}🟢get_visa_bulletin_notes(month)
Returns every lettered advisory note in a month's Visa Bulletin: the forward-looking text, e.g. "EB-1 India may become unavailable". Use it when the user asks whether dates are expected to advance, hold, or retrogress. For the chart dates themselves, use get_visa_bulletin or get_visa_bulletin_dv. An empty list means the month was loaded and had no notes; a month not on file returns not_found. Free, no sign-in required. Limit: 20 calls per minute per IP, then rate_limited. Not legal advice.
