DS-2019 explained without the embassy-speak
One page of paper decides your entire summer. Here is what the DS-2019 actually says, who issues it and why a typo on it can ruin everything.

The DS-2019 is a single sheet of paper, and it is the most important document of your program. Your sponsor generates it once you are accepted into their Summer Work Travel roster. Without it there is no visa interview, no SEVIS fee, nothing.
What is actually on it
- **Form start and end dates**: your legal working window in the US. Not a day more.
- **Sponsor name and program number**: the organization legally responsible for you.
- **Your name exactly as in your passport**. A mismatched birthdate or spelling error means trouble at the border.
If anything is wrong, ask for a corrected copy immediately. Sponsors fix these things fast when you catch them early, and slowly when you catch them late.
The 30-day rule nobody mentions
You may enter the US up to 30 days before your form start date, but you cannot work until that date. People arrive early, pick up "orientation shifts" and quietly violate their status without realizing it.
Do not lose it
You show this paper at the embassy, again at immigration, and possibly when applying for a Social Security number. Photocopy it, scan it, keep a copy in your email. Replacements take weeks because sponsors ship them from the US.
After the program ends
You get a 30-day grace period to travel inside the US, but you cannot work during it. Book return flights with that in mind. Overstaying the grace period does not just end this trip, it stains every future US visa application.
