Obama was due at the Blue House, the South Korean equivalent of the White House, today for a busy evening of meetings with Park, including a working dinner and a news conference.
The visit is Obama's first to Seoul since Park became the key US ally's first female president, but Park has been consumed for more than a week by the sunken ferry, a dark episode that keeps getting worse as divers discover more bodies.
"When our friends are in trouble, America helps, and we'll continue to do everything we can to stand with our Korean friends at this difficult time," Obama said in an interview published Friday by the South Korean newspaper JoongAng Ilbo.
After arriving here today, Obama headed first to the National War Memorial, where he laid a wreath in honor of victims of the Korean War and led a naturalization ceremony for 20 military service members and their spouses from 14 countries. He used the occasion to call for a comprehensive immigration overhaul in the US, saying he's going to "keep pushing to get this done this year."
