H1B Sponsorship Process at Splunk
Post-Cisco acquisition (March 2024), Splunk H1B petitions are now filed under Cisco Systems, Inc. as the legal employer. Splunk employees were transferred to Cisco's H1B sponsorship without requiring new filings — H1B portability provisions covered the employer change.
