There are few problems for most travellers, and no visa is needed. They can get a one-entry one-month visa at around US$7, or a two-entries three-month visa at US$10. These are best obtained at an embassy accredited the traveller's own country, but there should not be all too much problems getting one at the border. If there are regulations against you nationality, a small bribe, will soon make the system work wonderfully.
When you enter Morocco, you can stay here for 90 days (unless other stated). Extending your stay can be fixed quite easily, and by others, if you work. If you just want to stay longer, prepare for a small trip out of Morocco, or entering a complicated bureaucracy. Regulations state that you will have to put up an economical security, primarily by transferring a fairly large amount of money to a Moroccan bank. This is easily done, but you need to have some money, and the sums involved (around 20,000 dh) could very well be more than you'll be able to spend during the rest of your stay. Leaving Morocco, in order to return within a couple of days (and through a different port), is recommended.
Carrying a passport with stamps from Israel is no longer representing much of a problem, even if regulations does not seem to be all to clear yet. Check with a consulate before you leave.
Some nationals do not even need a passport, only a national identity card (if they have one), when they go on organized tours: Austria, Denmark, Finland, France, Germany, Iceland, Norway, Spain, Sweden, and Switzerland.
All visitors entering and leaving Morocco, must fill in entrance and exit cards. You will have to declare identity, purpose of visit, and places you have visited. It will not take more than a minute or two to fill these in, and the control with your accuracy is not to close.
