Marriage to a US citizen is no longer a sure way to get a Green Card, says American immigration lawyer Brad Bernstein. He said officials now check if couples really live together and share daily life. Applications are under tighter review, with more focus on genuine relationships. Couples who stay apart, even for work or study, may face rejection. Bernstein said officers do not rely only on legal papers and can open fraud checks if spouses do not share a home. US Citizenship and Immigration Services reviews the full relationship to see if the marriage was in good faith and not only for immigration benefit.

Even as China conducted large-scale military drills — including live-fire exercises and simulated blockades dubbed “Justice Mission 2025” — around Taiwan’s coast, everyday life largely went on as usual for residents, Al Jazeera reports. Many locals carried on routines like socialising and working without disruption, reflecting an enduring normalization of cross-strait tensions. While the exercises underscored Beijing’s growing assertiveness over Taiwan, they did not visibly alter civilian activities. The drills, widely covered in media and discussed online, highlight persistent geopolitical friction as China asserts claims over Taiwan, which it views as part of its territory. (PC: Al Jazeera)
