I came to the U.S. on ESTA - can I adjust status? 

So you entered the United States on the Visa Waiver Program, also called ESTA. And now you've either married a U.S. citizen or you're thinking about marrying a U.S. citizen. And you want to know, can you apply for adjustment of status - also called a green card application - based on that marriage. The answer is maybe, but the details are important.
