Employment verification letter for immigration: what USCIS reads

Immigration cases use two different employer letters. An experience letter is the employer’s proof of past or current work experience for an employment-based petition such as Form I-140. It describes what the person did, not just that they were on the payroll (8 CFR 204.5, Petitions for employment-based immigrants).

The second letter confirms a current job and pay. A sponsor filing the Affidavit of Support, Form I-864, may add a letter from their own employer, along with pay stubs, if it helps show income (USCIS, Form I-864, Affidavit of Support). Here the letter is about the sponsor, not the immigrant.

Neither letter has a USCIS form. The employer writes it on letterhead, signs it, and the applicant or their attorney files a copy with the petition.

An employer the person worked for writes it: usually a direct supervisor who knows the duties, or HR working from the supervisor’s notes. The regulation allows letters from trainers as well as employers (8 CFR 204.5, Petitions for employment-based immigrants). For Form I-864, the sponsor asks their own employer’s HR or payroll for the letter.

1. Ask your attorney which letter the case needs and which experience it must prove.
2. Send HR or your former supervisor a draft of the duties, matched to the job requirements in the petition.
3. Ask them to rewrite the duties in their own words, print the letter on letterhead and sign it.
4. Collect pay records and tax records that back the dates in case the letter is questioned.
5. Get a certified English translation of any letter written in another language.

• A one-line letter that confirms dates and title but describes no duties.
• A letter that omits the writer’s title or address, both named in the regulation.
• Duties that do not match the experience claimed in the labor certification.
• A letter in another language filed without a certified translation.
• A letter that comments on the employee’s immigration status or eligibility, which HR cannot confirm.

Start by naming the filing. The table compares the two letters immigration filings use and the rule behind each.

The general rule is in 8 CFR 204.5(g)(1): evidence of experience comes as letters from current or former employers or trainers (8 CFR 204.5, Petitions for employment-based immigrants). Each letter gives the writer’s name, address and title and a specific description of the duties performed or training received (8 CFR 204.5, Petitions for employment-based immigrants).

Some classifications add a length of experience. A skilled worker needs at least two years of training or experience (8 CFR 204.5, Petitions for employment-based immigrants). An advanced-degree professional with a bachelor’s degree shows at least five years of progressive post-baccalaureate experience through employer letters (8 CFR 204.5, Petitions for employment-based immigrants).

Progressive experience means the jobs grew in responsibility over time, so the letter should show each title held and the dates of each, not only the last one. Write the dates as full dates, month, day and year, so the totals can be counted.

Every sponsor files a copy of their federal tax return for the most recent tax year, including W-2 forms and every Form 1099, or explains why no return was required (USCIS, Form I-864, Affidavit of Support). Use the current edition of Form I-864, dated 08/24/26 (USCIS, Form I-864, Affidavit of Support). USCIS lists pay stubs from the most recent six months and a letter from the employer as extra items the sponsor may add if they help qualify (USCIS, Form I-864, Affidavit of Support).

This letter is short. It confirms the sponsor’s title, start date, full or part time status, salary or hourly rate and pay frequency. It adds that the job is expected to continue only if HR can say so truthfully.

Old employers close, merge or refuse. The regulation covers this: if letters are unavailable, other documentation of the experience will be considered (8 CFR 204.5, Petitions for employment-based immigrants).

Your attorney may suggest alternatives, for example sworn declarations from former coworkers or supervisors, pay records, tax records, or contracts that show the role. Explain in writing why the employer letter cannot be obtained, and keep any refusal email.

HR’s job is to state facts the company can stand behind. A certified translation is a full English translation with the translator’s statement that it is complete and accurate and that they are competent to translate; USCIS requires one for any foreign-language document (8 CFR 103.2(b)(3), Translations).

• Use the employee’s full legal name as on the passport, and list other names used at the company.
• Give each title held with exact start and end dates, and the weekly hours.
• Describe duties in concrete terms, such as the systems used, the products built or the team supervised.
• Add the writer’s phone number and email so the letter can be checked.
• Leave out opinions on immigration status, medical or leave details and anything the records do not show.

8 CFR 204.5(g)(1) does not state an age limit for an experience letter (8 CFR 204.5, Petitions for employment-based immigrants). A recent letter still reads better, and attorneys usually ask for one dated close to filing.

Some deadlines around the letter are firm. A labor certification expires 180 days from the date of certification, and USCIS must receive the I-140 based on it within that period (USCIS, Form I-140, Immigrant Petition for Alien Workers). Plan the letter well before that date.

• 8 CFR 204.5, Petitions for employment-based immigrants: Experience is shown by letters from employers or trainers giving the writer’s name, address and title and a specific description of duties; other evidence is considered if letters are unavailable; skilled workers need at least two years and advanced-degree holders five years of progressive experience.
• USCIS, Form I-864, Affidavit of Support: Sponsors file their most recent tax return with W-2 forms and 1099s, or explain why none was required, and may add pay stubs from the most recent six months and a letter from their employer; the current edition is dated 08/24/26.
• USCIS, Form I-140, Immigrant Petition for Alien Workers: Labor certifications expire 180 days from the date of certification, and an I-140 based on one must be received within that period.
• 8 CFR 103.2(b)(3), Translations: A foreign-language document filed with USCIS needs a full certified English translation and the translator’s certification of competence.
