"This vacation changed our life," said Vasyl Prishchak, who along with his wife owns a cosmetics company with stores in Ukraine, Russia, Belarus and Kazakhstan. "We don't know how we return to Ukraine and what we will do, we will begin from zero, from scratch."
They are unsure if their house near a military base in Kyiv is still standing and say they are financially imperilled because their family business has been forced to close.
The family had been to Hawaii several times before to visit with longtime friends Borys and Beata Markin. Vasyl and Borys have been friends for about 30 years and are both avid ocean paddlers.
The community has helped the family with everything from schooling and immigration questions to financial help and a place to stay.
Until last week they were staying at a loaned home in Kailua, a beach town on the windward side of Oahu, but family friend Beata Markin said they've now secured a small cottage in Kaneohe where the owner is allowing them to stay free of charge for as long as they need.
"They have nowhere to go," said Markin, who was born in Hungary and has lived with her Ukrainian husband in Hawaii for eight years. "I think it's our responsibility to make sure they are OK here."
An online fundraiser organized by canoe club members has so far raised more than US$32,000 for the family.
"Sadly, we can't help all the Ukrainians, but we can help this family," wrote Charlotte Johnson, an Oahu resident who helped set up the fundraiser.
"The banking system in Ukraine is a shambles, and they cannot access any of their accounts. None of us can even imagine going on a vacation only to find the life left no longer exists."
Globally, tens of thousands of Ukrainians were overseas when Russia invaded. In addition, the United Nations said Wednesday that more than 4 million people have fled Ukraine since the war began, the biggest movement of people in Europe since World War II.
While US officials could not immediately say exactly how many Ukrainians were in the US on tourism or business visas when the war began, the Department of Homeland Security expects an estimated 75,000 Ukrainians to be eligible to apply for Temporary Protected Status, which will allow them to stay in the country for 18 months.
Though the Prishchak family hopes to eventually return home, they are applying to stay under the program, which was created in 1990 to allow people to remain in the US because of civil strife or natural disasters in their home countries. Permission is extended until Homeland Security deems conditions are stable enough for people to return.
The US is also expanding efforts to help Ukrainian refugees elsewhere. While in Brussels to meet with European allies last week, President Joe Biden said the US would admit up to 100,000 more Ukrainian refugees and provide US$1 billion in humanitarian assistance to countries affected by Russia's invasion.
Prishchak's oldest daughter, 16-year-old Mariia, said her excitement about vacationing in Hawaii was quickly replaced by fear for loved ones.
In the first week, they took a lot of photos, she said, but "one day we disappeared from all social media because it is no time to post these photos when people suffer."
Mariia said she had always dreamed about going to school in the US, but not under such terrible circumstances. She checks in with friends and family every morning and night to make sure they are safe.
"Every day, I hope that next day everything will be finished," she said. "And it's awful. I'm confused and I can't do anything else except for thinking about the situation."
Her father said it's difficult being in the safety of a tropical paradise while other men his age are back home fighting and not allowed to leave the country.
"It's a really terrible feeling that eats away at you from inside when you understand that all your close relatives are now in a very complicated situation," the elder Prishchak said in Russian.
"And there's no way you can help them stop this absolute insanity. It's a feeling that simply eats you up inside, you could say. A horrible sensation, an inner guilt that I'm here and not there."
