最新报道:The U.S. State Department has announced new visa requirements for citizens of several countries, including Nigeria, Venezuela, and Myanmar, mandating them to post bonds ranging from $5,000 to $15,000 to obtain certain visa types. The policy, effective immediately, aims to reduce overstays and ensure compliance with visa terms. Officials stated the bond amounts are based on risk assessments of each country's visa violation rates. Critics argue the measure unfairly targets developing nations, while supporters claim it will strengthen immigration enforcement. The bonds will be refunded upon departure from the U.S. within the authorized period.
