First thing you must do just to be eligible for the draw is purchase a general hunt license. You will not be able to aplply without it. To hunt big game in New Mexico you will also need to get the Habitat improvement stamps, you can buy them with your gen hunt license or later down the road before you hunt. Don't go hunt without your stamps, I accidentally did once. Once you have purchased your license go ahead and apply for all the hunts you want. You will have to put up the full amount for each tag at the time your applying. There is a non refundable $5 application fee for every hunt you apply for. You can use credit or debit cards. Once the drawing takes place you will get refunded for any tags you didn't draw with exception to the application fees. If you change your mind after you put in an application you may cancel it and put in a new application. But you will not get refunded for that cancelled application until the draw.
