If i travel to the US with B1/B2 visa and get married there, can i still travel with my B1/B2 visa while my spouce nonimmigrant visa for spouse (K-3)?
It is better to use K-1 visa if you intent to marry in the US.
If using B1/B2, provided you get I-94 for 6 months of stay, wait at least 90 days after entering before marrying.
You may as well consult an immigration lawyer.
Thanks for the response, but if i got married after 90days and leave the US to my home country can i still travel with my B1/B2 visa to the US?
Yes you can as far as the intent is just to visit.
