Do I need a U.S. social security number and do I have to pay U.S. taxes?
Yes. Trainees and interns should present themselves at the nearest Social Security Office with their passport and Form DS-2019. In order to find a Social Security Office closest to you, please refer to the Social Security on-line Office Locator http://s3abaca.ssa.gov/pro/fol/fol-hom.html
Trainees and interns must also pay U.S. federal and state taxes. State income taxes vary (and some states do not have an income tax), but the federal income tax is indexed by the level of your wage. You should expect to pay about 25 percent of your gross salary in federal income taxes. Federal and state income taxes will automatically be deducted from your paycheck by your employer.
Prior to a intern/trainee’s arrival in the U.S., the BACC will send him/her a packet of information which includes a Social Security letter and application form and IRS Publication 513 which outlines the procedure for paying U.S. taxes.
Can I request a J-1 Visa if I have had one before?
Yes. Trainees can request it as long as at least two years have passed since you last held a J-1 visa, and as long as the field in which you wish to receive training is different from the field of training for the last visa.
Interns may remain in the U.S. as a participant in a designated internship program for a maximum of 12 months. Interns may participate in additional internship programs as long as they maintain student status or begin a new internship program within 12 months of graduation.
