Short answer: Preserve the message or post, the account or phone number that sent it, the date and time, the platform, and enough surrounding context to understand what happened. Avoid confronting the sender just to create more evidence.
This page provides general information and organization guidance only. It does not decide whether evidence is legally sufficient, tell you what to file, or replace advice from a licensed immigration attorney or DOJ-accredited representative.
Capture context before content disappears
Save screenshots that show the account name, date or time, message text, and surrounding conversation when relevant. If there is a direct URL, save it. If the platform allows data export, consider preserving an export in addition to screenshots.
Keep a copy of any image, audio, or video attachment. If the account later disappears, your saved material should still show when and where you captured it.
Keep a contemporaneous log
A simple log can record the date, platform, sender, what occurred, whether you blocked or reported the account, and where the saved file is stored. Write only what you know. Do not identify an anonymous account as a specific person unless you have a factual basis for that identification.
If the harassment is part of a longer pattern, separate individual incidents rather than combining several dates into one vague entry.
Do not create risk for evidence collection
You do not need to keep an abusive account unblocked simply to collect more messages. Personal safety comes first. If you believe you are in immediate danger in the United States, use appropriate emergency or law-enforcement resources.
For immigration purposes, preserve the material and let a qualified representative assess relevance and any privacy or authentication concerns.
A practical way to organize this
Use a simple evidence index with columns for date, source, file name, short description, language/translation status, and where the original is stored. Keep uncertain information marked as uncertain. Do not change an original document to make it fit a timeline or another record.
If you are preparing for an attorney meeting, bring the index and the records you already have. You can also use the free Evidence Toolkit to organize a timeline, evidence inventory, missing-evidence list, witness list, and attorney questions.
Check current sources before filing
Agency rules can change, and the rules for USCIS, Immigration Court, and the Board of Immigration Appeals are not identical. Verify the current source that applies to the forum handling the case.
- USCIS: Form I-589 and current instructions
- EOIR Policy Manual: Documents
- Immigration Justice Campaign: Asylum application and supporting evidence
