I changed my job from company A to company B this month. The h1b stamping on my passport is with company A (old company), and is valid till Feb 2021. Company B (new company) filed an H1b transfer and got an approval in premium. Question: Can I travel to Europe for a week and then return to US, without a visa stamping from company B? I will still have a valid h1b stamping on the passport, but from the old company (company A).
