Documents Required for H1B Extension
This USCIS H1B extension documents checklist can be used for H-1B transfer or amendment as well.
If you are looking for Visa stamping in US Embassy, then you should follow the H1B Visa Interview Documents.
#1 Form I-129
Form I129 is an official USCIS form used for filing H1B application.
#2 LCA – Labor Condition Application
Un-expired LCA from past H1B can be re-used but the total H1B term will be reduced by LCA validity.
#3 Most Recent I94
- Check last approved H1B i797A for attached paper i94.
- Or if you last entered USA by any port of entry, download i94 from CBP website.
- Or if you got your i94 extended after passport renewal at any Land Border like Laredo, TX or San Diego, use your paper i94 copy.

#4 Most Recent Entry to US Immigration Stamp
Check US immigration stamp in your Passport that’s stamped at port of entry.
#5 Most recent 3 Pay Stubs
Pay Slips or Salary Statement. Most employers use ADP as payroll provider. You can download your payslips from adp site.
#6 H1B Visa Stamps in Passport (If Any)
Submit color copy of H1B visa stamps from your passport.
It does not matter if the visa stamp is in old expired passport or the stamp has been marked ‘cancelled without prejudice’.

#7 Education Degree and Mark Sheets
Degree certificate is mandatory for H1B to prove you finished your education.
#8 Proof of Specialty Occupation
A letter from university professor attesting job requirements require special knowledge is highly recommended in addition to other documents like similar job postings, job descriptions from O*net government website.
Note that H1B specialty occupation criteria requires that you should have at-least a bachelor or masters degree.
#9 Current and OLD Passport Biometric Page
Submit color copy of passport pages with your photo and address. Passport should be valid for at-least next 3 months.
All old and expired passport’s biometric pages are required.
#10 (Optional) i140 receipt or approval
i140 approval copy is required only if you are filing H1B extension after 6 year quota.
If your employer has not shared i140 with you, you can use USCIS FOIA request to extract i140 receipt copy.
#11 Proof of Employer Employee Relationship
Third party consulting companies need to prove that they have all rights to hire, fire and control daily work assignments of H1B workers.
If you are going to work in an EVC (Employer client vendor) model, then you should use the document checklist to prove employer employee relationship to avoid RFE.
#12 Client Letter
A written letter from end client for the period of project/ work clearly mentioning start and end date is required from consulting companies. If you are working full time with end client, then this letter is not needed.
#13 H1B Work Itinerary
Third party consultants need to provide a detailed itinerary of work assignments at the end client location. A sample H1B work itinerary is given below.
A new LCA is required for H1B extension. LCA should be approved before filing an H1B extension, transfer or amendment.
A detailed work itinerary is required to prove the actual work assignment and hours at the end client location. USCIS is pretty strict these days and asks for work location address and hours of work to be performed.
You will need the same set of requirement that you have used for H1b extension to file H1B change of status including last 3 pay stubs, H1B cap subjected receipt number and an approved LCA.
Payslips are required for filing H1B extension.
Most recent 3 bi-weekly pay stubs are required for filing H1B transfer.
Salary slips prove your maintenance of H1B status in case of H1B extension, transfer or amendment.
Payslips are not required if you are filing H1B extension or transfer from outside USA.
Legally, you can file for H1B transfer immediately after your H1B lottery approval on Oct 1, but, it is strongly recommended to at-least work for sponsoring employer for at-least 1 day to avoid RFE.
