Over a year ago, I married a woman from Belarus. We submitted her green card application in the United States. She wants to go home for a visit but cannot because she's afraid of missing her green card interview. Is there some way we can speed up this process?

You might as well ask whether you can make the earth move faster around the sun. Government bureaucracies, like planets, operate according to their own natural laws. They tend to move slowly, and they don't take kindly to questioning or prodding.

But, here's the good news: The longer the wait (and the average wait seems to be at least a year), the more solid your marriage is going to look by the time you reach the green card interview. The two of you can use these months to improve and prepare the evidence of your bona fide marriage that you'll bring to the interview: copies of shared home rentals or title, joint health insurance, car insurance, credit cards, and more. If these requirements are new to you, see Nolo's Fiancé and Marriage Visas: A Couple's Guide to U.S. Immigration. It covers everything talked about here and more.
