I 129 mailing address

You're looking for a mailing address that starts with "I 129". I'm assuming you're referring to the I-129 form, which is a non-immigrant visa petition used to sponsor foreign workers in the United States.

The mailing address for the U.S. Citizenship and Immigration Services (USCIS) to submit Form I-129 is:

U.S. Citizenship and Immigration Services P.O. Box 660167 Louisville, KY 40266-0167

Please note that this is a general mailing address and may not be applicable for all types of I-129 petitions or for petitions that require expedited processing. It's always a good idea to check the USCIS website or contact the USCIS Contact Center for specific guidance on submitting your petition.

Additionally, you can also check the USCIS website for the correct mailing address for your specific petition type, as it may vary depending on the type of petition you are submitting.
