“For me, they were like a princess,” she said. “And I kept those pictures in my mind, and I made a wish that one day I would like to be one of those ladies.”

Today, at the age of 30, she lives with her husband, Joseph Davis of Fresno, California, in an air-conditioned, three-bedroom house with a driveway and basketball hoop, surrounded by flower beds and a well-kept lawn.

“My family keeps saying, ‘You got it. You got your dream now,”’ she said.

But unlike many other foreign husbands, Mr. Davis, 54, did not take his wife home with him, choosing instead to settle down in northeastern Thailand, a region known as Isaan.

He is part of an expanding population of nearly 11,000 foreign husbands in the region, drawn by the low cost of living, slow pace of life and the exotic reputation of Thai women — something like a brand name for Western men seeking Asian partners. “Thai women are a lot like women in America were 50 years ago,” said Mr. Davis, before they discovered their rights and became “strong-headed and opinionated.”

“The women now know they are equal,” said Mr. Davis, a retired Naval officer who has been divorced twice, “so the situation is not as relaxed and peaceful as it is between an American and a Thai lady.”

It is easy to spot the foreigners’ homes, with their sturdy walls and red-tiled roofs, an archipelago of affluence among the smaller, poorer houses of their new neighbors and in-laws.

Mixed couples are common on the streets and in the markets of Udon Thani. One street where Western men gather to eat and drink is popularly known as “Foreign Son-in-Law Street.”

“There are villages in Isaan that are almost entirely comprising foreign houses, where the whole village is almost entirely houses purchased by foreigners for their Thai ladies,” said Phil Nicks, author of “Love Entrepreneurs: Cross-Culture Relationship Deals in Thailand.”

Isaan is one of the poorest parts of the country, the source of most low-wage workers in Bangkok and the home of many of the women who work in the entertainment industry in the capital.

Some of the earliest Thai-American marriages were in Udon Thani, the site of a U.S. air base in the 1960s during the Vietnam War. In the following years, most Americans left, sometimes taking a Thai wife with them. Now the presence of American and European men is growing again. “In the northeast where this phenomenon is strongest, a huge majority of the women there are looking for a foreign boyfriend or husband, and I think some of them can be quite assertive, and aggressive in their pursuing of a foreign man,” said Mr. Nicks.

A clash of expectations strains many marriages, and more than half end in divorce, said Prayoon Thavon, manager of international services at Panyavejinter Hospital in Udon Thani.

While the men — many of them retired and living on pensions, many disappointed in their lives and marriages at home — may be seeking an emotional connection, the women are generally motivated by economics, said Mr. Prayoon, who provides counseling for mixed couples.

“For some ladies it is just money, money, money,” he said. “Getting married has become a business more than love. People want to improve their social status. Sometimes these ladies spend the husband’s money, use it all, then he’s cut out. There are many cases like that.”

Even though many men are retired and living on a fixed income, they are expected to help support their wives’ extended families, beginning with a dowry of several thousand dollars.

“When you get married in Thailand you are marrying the whole family, the whole village,” Mr. Prayoon said. “Often the lady expects that, but the man doesn’t understand.”

There seems to be less concern about differences in age, with many bridegrooms in their 50s or 60s or even 70s.
