If you are filing Form I-130, I-129F, or I-751 and want to submit your messages, export each conversation to PDF with names and timestamps visible, keep every file under 12MB, and attach a certified English translation for anything not in English. Chat history is supporting evidence, not required evidence — this guide covers what that means in practice.

What USCIS actually asks for

Start with an uncomfortable fact: chat logs do not appear on any USCIS list of required evidence.

For a spousal petition, the regulation at 8 CFR 204.2(a)(2) names what must accompany Form I-130 — photographs of both spouses, a marriage certificate issued by civil authorities, and proof that all prior marriages were legally terminated. Messages are not on that list.

For Form I-751, the regulation at 8 CFR 216.4(a)(5) lists six categories of evidence that a marriage is bona fide:

Chat history lives in that last category. It is the catch-all, and the weight given to anything in it is discretionary.

That is not a reason to skip it. It is a reason to be realistic about what it does. A year of daily messages does not replace a joint lease or a shared bank account — but it does something those documents cannot: it shows a relationship existing continuously in time, across distance, in your own words. For couples who lived apart before the petition, that is often the only evidence of the period before you shared an address.

What the messages are doing in your specific filing

Filing What message evidence supports
I-130 (spouse) An ongoing marital union, especially for periods when you lived apart or in different countries
I-129F (K-1 fiancé) A continuing relationship and communication between two people who have met in person
I-751 (remove conditions) That the marriage was entered in good faith, covering the conditional-residence period

If you are filing a K-1 petition, note that messages do not establish the in-person meeting requirement — that is what boarding passes, passport stamps, and photographs together are for. Messages fill the space between visits.

How much chat history to include

USCIS does not publish a page count, a date range, or a message quota. Anyone who gives you a specific number is guessing. What the regulations say is that officers weigh the evidence at their discretion.

What follows from that is a question of shape, not volume:

There is also a hard practical ceiling, and for most people it decides the question.

The 12MB limit is the real constraint

If you file online, USCIS states in its tips for filing forms online that uploaded evidence must be:

A year of messages with images attached will blow past 12MB long before you finish. So the export has to be split, and the sensible way to split it is by date range — one file per quarter, named so an officer can see what each covers without opening it.

This is worth planning before you export rather than after. Re-cutting a 90MB PDF into compliant pieces is tedious; exporting quarter by quarter in the first place is not.

Splitting by date also makes the exhibit easier to reference in a cover letter, since you can point to a specific file for a specific period.

What each page has to show

An officer looking at your printout needs to be able to tell who was talking and when, without taking your word for it:

A PDF export showing the header block and two messages with sender names, phone numbers, dates and times
An export that satisfies the checklist above: both parties named with phone numbers, the date range of the conversation, the message count, and a timestamp on every message.

Also worth knowing: under 8 CFR 103.2(b)(5), USCIS may request an original document at any time and set a deadline for producing it. Keep the source conversation on your device until your case is decided. Do not delete a thread after exporting it.

Export a conversation without a computer

Save any chat as a clean PDF with sender names and timestamps intact, right on your iPhone.

Non-English conversations

This one is not discretionary. 8 CFR 103.2(b)(3) requires that any document containing a foreign language be accompanied by a full English translation, certified by the translator as complete and accurate, along with the translator's certification that they are competent to translate from that language into English.

Three things people get wrong:

The translator does not need to be licensed or accredited, and it does not have to be a commercial service. It does need to be someone competent in both languages who is willing to sign the certification. In practice, that usually rules out the petitioner and the beneficiary translating their own conversation.

If your thread is mixed — English with stretches of another language, which is normal for couples — the foreign-language portions still need certified translation.

Exporting the conversation, app by app

WhatsApp

WhatsApp has a built-in export. Open the chat, tap the contact name, scroll to Export Chat, and choose whether to include media. It emails you a .txt file of the conversation.

Be honest with yourself about whether that is enough. For many filings it is: the file is complete, it has timestamps, and it costs nothing. Its weakness is that it looks like a text file rather than a conversation — no bubbles, no visual sender distinction — and long chats arrive truncated when media is included. If a plain transcript reads clearly for your case, use it and skip everything below.

iMessage and SMS

Apple's Messages app has no export function at all. Your options are a Mac (if your messages sync there, you can print a conversation to PDF from the Messages app), a desktop tool that reads an iPhone backup, or an on-device app that captures the conversation from the screen.

A conversation reassembled in an export app, with sender names and a timestamp above each message
However you capture it, check the result before exporting: each message needs a sender and a timestamp, and the sequence has to be unbroken.

Instagram, Messenger, Telegram, Signal

Meta offers a data download for Instagram and Messenger through account settings, but the output is a data archive rather than a filing-ready document, and it can take days to arrive. Telegram Desktop exports a chat to HTML. Signal has no per-conversation export.

For these, screen capture is usually the practical route.

Paper filing versus online filing

Online: the 12MB, format, and no-encryption rules above apply to every file you attach.

Export format options: PDF, CSV and plain text
PDF is the format to pick for a filing. CSV and plain text are useful for your own records, but USCIS online filing accepts PDF, JPG and JPEG.

Paper: print single-sided, keep each conversation as its own labeled exhibit, and include a cover sheet naming the participants, platform, and date range. Send copies, not originals, unless the form instructions say otherwise — and keep your own complete set.

Either way, do not submit a USB drive, a cloud link, or a video file. Evidence has to be a document an officer can read in the file.

Frequently Asked Questions

Does USCIS accept text messages as evidence of a relationship?

Yes, as supporting evidence. For Form I-751, chat history falls under 8 CFR 216.4(a)(5)(vi), the category for other documentation establishing that a marriage was not entered into to evade immigration laws. It is not required evidence for any of these forms, and how much weight it carries is at the officer's discretion.

How many pages of chat history should I submit?

USCIS does not publish a number. Consistent contact spread across the relevant period is more useful than a large volume from a short window. If you file online, the 12MB per-file limit is a more practical guide than any page count, and splitting the export by date range is the usual way to stay under it.

Do I need to translate messages that are not in English?

Yes. 8 CFR 103.2(b)(3) requires a full English translation certified by the translator as complete and accurate, plus the translator's certification that they are competent to translate from that language. You submit the translation in addition to the original, not instead of it.

Can I use screenshots instead of a PDF export?

Yes, screenshots are acceptable, but they need to be legible at print size and show names and timestamps. The common failure is shrinking many screenshots onto a page until the text cannot be read. A PDF export of the thread is easier to read and easier to keep under the file size limit.

Should I delete the conversation after exporting it?

No. Under 8 CFR 103.2(b)(5), USCIS may request an original document at any time and set a deadline for producing it. Keep the conversation on your device until your case is decided.

Will editing out private messages hurt my case?

Removing genuinely irrelevant material is normal. The risk is edits that break the visible sequence of a conversation, since a thread that jumps without explanation raises the question of what was taken out. If you excerpt, excerpt whole exchanges and label the date range you are covering.

Before you file

This article explains what the regulations say and how to produce a readable exhibit. It is not legal advice, and immigration cases turn on facts that a general guide cannot see. Requirements also change: verify the current edition of your form's instructions on uscis.gov before filing, and if your case has any complication — a prior denial, a prior marriage under review, an abuse or good-faith waiver — talk to an immigration attorney rather than a website.
