Ft. Lauderdale Chamber of Commerce, of which I am a member. During the conversation he revealed that he had started a residency process, but he was anxious about how long the process would take. Fortunately, residency based on marriage to a U.S. citizen wife is in most cases rather fast -- less than six months.
He was anxious because his work requires foreign travel and the advance parole document can also take six months to obtain. Advance parole is the name for the travel permission given by Immigration for persons who are adjusting status to resident in the U.S. What he did not know was that emergency advance parole is an option available to him. Emergency advance parole can be obtained within 10 days.
In order to obtain emergency advance parole, the foreign national must submit the correct fee, the application and necessary evidence. The evidence would include such things as letters from physicians abroad certifying the urgent need for travel. Precise evidence depends on each person's case.
