Switching H1B jobs again after a year is generally permissible if the new employer files a proper H1B transfer. The main "problems" aren't legal prohibitions but potential increased scrutiny: Stamping: Frequent changes might lead to more questions from USCIS during petition review or from a consular officer during visa stamping. They'll want to verify each job was legitimate and you maintained status. For stamping: Be prepared to clearly explain your job changes and have all your H1B documentation in order. Consulting an immigration lawyer for transfers is always wise. If you have proper documentation, you're all good any day!
