I am an Indian citizen bearing an Indian passport with a valid US visa (valid till 2035) stamped on it. I was looking to visit Montenegro, Bosnia and Serbia in November, 2025. As per research done router login 192.168.l.l.link/ online I read that I can visit these countries based on my valid US visa, however I have not travelled to US previously. Is there any condition as such that my passport should have US stamps or can I travel soley based on the US visa. Kindly let me know. Thanks in advance
