Suwat Kaewsook, director of the Department of Consular Affairs' Protection of Thai Nationals Abroad Division, said women must understand more about foreign citizenship if they wish to live overseas.
"Living abroad with foreign husbands is not always as wonderful as a lot of people expect, so you must learn more about your [legal] rights in a foreign country," Mr Suwat said.
He was speaking to around 100 people who attended a seminar entitled "Across the Universe: Cross Cultural Marriages", which was hosted by Rangsit University's International College.
Kanokrat Nimsamoot Booth, chair of the Federation of Thai and Foreign Spouse Networks Association of Thailand, said she had launched a website _ www.thaiforeignspouse.com _ to help Thai women who have problems with their foreign husbands.
Ms Kanokrat revealed that just over two months after the site's launch, around 200 women had sought advice on their marriages.
"The main problem is that their foreign husbands have affairs and want a divorce, despite them having kids together," said Ms Kanokrat.
She said many of the women did not have enough money to sue their husbands for abandonment and sought help from her association.
Somkid Homnet, a consultant working with the Department of Labour and Social Welfare who carried out a study concerning foreign spouses in Udon Thani province last year, presented the findings at the seminar.
He discovered that there were up to 5,700 foreign spouses from 33 countries living in the province.
Most of them were German, British, American, Australian and French, and they had an average monthly income of about 100,000 baht.
The study also found they met their wives through matchmaking companies, the internet and friends or relatives.
There are currently around 50,000 Thai women married to German men, 30,000 married to French men, 30,000 to Americans, 25,000 to Australians, 10,000 to Britons, 8,742 to Swedes, 7,937 to Taiwanese, 3,000 to Austrians, 2,891 to Finns and 1,086 to Danes, according to statistics compiled by the Foreign Ministry.
