Now, coming to the topic of birth tourism.
Birth tourism is a real phenomenon, and there is documented evidence of organized operations, particularly involving Chinese nationals in Southern California. Several operators have been prosecuted and convicted for immigration and visa fraud related to these schemes.
That said, it is important to keep the scale in perspective. The United States records roughly 3.5 million births each year, and there is no official government count of birth tourism cases. Independent estimates suggest that the number is relatively small compared with the total number of births in the country. While the issue is real and has resulted in criminal prosecutions, it is not as widespread as some news coverage or political rhetoric may suggest.
