Specific Instructions
The respondent must have been born overseas.
The respondent’s birthplace (country) should also be assessed.

Protocol
About how long have you been in the United States?
[2-digit entry] ________
If less than 1 year given as response, code the answer as "0"; enter "00-94" for 0-94 years, enter "95" for 95+ years, 97-Refused, 99-Don’t know
Personnel and Training Required
The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews.* The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.
* There are multiple modes to administer this question (e.g., paper-and-pencil and computer-assisted interviews).
Equipment Needs
While the source instrument was developed to be administered by computer, the PhenX Working Group acknowledges these questions can be administered in a noncomputerized format (i.e., paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer or handheld computer to administer a computer-assisted questionnaire.
