Depending on your class of admission (i.e., the sort of nonimmigrant you are classified as), the documentation you'll need to submit will vary greatly. You'll need to visit the I-539 instructions linked above to discover just what is asked of you document-wise depending on your class of admissions. For the most part, this will probably include evidence of certain relationships, whether personal or business-related. Unless otherwise requested, you should send copies of documents requested. If you send the original, know that there is a chance it will not be returned unless you specifically request it. Any document you submit in a foreign language must be accompanied by a translation in English. You must also include proof of your translator's qualifications. Regardless of the class of your admission (save for one or two exceptions) or the documents involved with your I-539 submission, there is a $290 fee required to submit your I-539. The USCIS requests that this $290 is submitted by check or money order. When writing your check or money order, you'll need to write as payable to U.S. Department of Homeland Security. Do not abbreviate it when writing your check. Certain applicants will be required to make a biometrics service appointment (the USCIS will notify you if this is the case, as well as when and where to attend). For those required to do this, there is an $85 fee included. Submit this in the same way you would the $290 fee. Depending on your location, where you file your I-539 will vary. Call 1-800-375-5283 or visit www.uscis.gov/I-539 to figure out where to file your I-539 form. Remember to include all of the documentation requested when filing your I-539. Some I-539 filings are eligible to file online. Check the website www.uscis.gov and look under "FORMS," and again under "E-Filing and Online Service" to see if you are able to e-file your I-539.

To start the last phase of the game, the draw pile must be emptied. When it is, don't shuffle. You simply stop drawing from the middle. When you can no longer draw, you rely solely on your hand. Keep playing out of it until there are no cards left in your hand. If you can't play, you still have to pick up the discard pile and put it in your hand. Remember, you have to play a card if you can. When it's your turn and you don't have a hand, play one card from your face-up cards. If you have multiple cards of the same rank, such as 2 jacks, you can play them both at the same time. If you can't play a card, you follow the same rule as before and pick up the discard pile. Once you pick up a pile, you must play all of those before playing from your cards on the table. When it's your turn and you've played all your face-up cards, pick a card that's face-down on the table. Don't look at it to choose. Simply flip it over. If it plays on the current card by being equal or higher, you can play it. If not, you must pick up the discard pile. If you pick up the discard pile, you must play those before continuing to play your face-down cards. You must play all your face-up and face-down cards to win the game. The first person to do so ends the game. The game can continue after the first person is out, but it's more fun to start another game instead.
