The provided documents do not confirm whether you can renew your Texas driver's license using only an H1B Receipt Notice (Form I-797C), or if you must wait for the Approval Notice.

Addressing Your Questions

You asked several specific questions about renewing your license with a pending H1B extension. Here is what the provided documents say:

**Using a Receipt Notice:** The documents do not state whether you can bring your H1B Receipt Notice (Form I-797C) to the Texas Department of Public Safety (DPS) for renewal, nor do they confirm if Texas DPS rules permit using it as proof of lawful presence.

**Waiting for the Approval Notice:** The documents do not specify whether you need to wait for the Approval Notice to renew your license.

**SAVE Verification:** The documents do not state whether the SAVE system can verify your lawful presence while an H1B petition is pending.

If you apply for a renewal and DPS cannot immediately verify your lawful presence electronically, they will initiate an additional verification through the SAVE system. A second-stage verification takes 10 to 13 business days. If a third stage is required, it can take up to 25 additional business days. DPS will issue an instruction letter within 48 hours after receiving the response from the Department of Homeland Security.

If a SAVE case is initiated, you can check its status online using USCIS SAVE CaseCheck. You will need your date of birth and an immigration enumerator, such as a Form I-797 Receipt Number or an I-94 number.

There is no official rule for this in the provided documents, but it is often worth visiting a Texas DPS office with your Receipt Notice and current immigration documents to ask the clerk if they can initiate a SAVE verification case for you.
