HenryKnows tools (4)

write = sends, deletes, buys or posts
  • ask_henryFree

    Ask HenryKnows a question about F-1/J-1 student immigration, SEVIS, OPT, CPT or related rules and get a cited answer. Ask in the person's own terms; do not add identifiers. Answers take 10–40 seconds. Read-only: nothing is stored.

  • connectFree

    Connect to the HenryKnows page the person is watching (its light turns green) and get the session for share_to_page. Only for people who gave you a session code or asked to follow along on a page. Side effects: creates a session, or links the one the person gave, and returns that session and the page's watch link; a new session starts each time it is called without a code; nothing is deleted.

  • search_sourcesFree

    Search HenryKnows' knowledge base (regulations, SEVP/USCIS guidance, Federal Register rules) and get the matching passages with their source links, so you can read and cite the text yourself. Fast; no model call. Read-only: nothing is stored.

  • share_to_pageFree

    Add a question and its HenryKnows answer (or a search and its passages) to the thread on the HenryKnows page the person connected, so they can see it there with its sources. Only for people who connected a page. Side effects: appends one entry to that page's thread, kept 24 hours; nothing else changes.
