How often can I visit the U.S. on a B1/B2 visa?

There's no specific limit on number of visits, but:

• Visits should be temporary and for legitimate purposes
• Spending too much time in U.S. (more than 6 months per year) may raise questions
• CBP officers may question frequent long stays
• You must maintain ties to your home country

Rule of thumb: Spend more time outside U.S. than inside to maintain non-immigrant intent.
