I have tried looking for places that will stamp it if I decide to stay a little longer then 90 days or will stamp it just to add to it, but have not found anything that gives me a direct answer. Just don't feel like getting into trouble while here or having issues trying to go back home if they see I was there longer and did not get another stamp.
The questions are:
Where can I get my passport stamped that is not to far from Venice, Italy?
How much trouble will I get in if I am here more than 90 days?
Check with the Italian consulate or embassy in your country. Don't go to Italy and leave it to the last minute. You might have to submit an application and the answer might take time so it is likely that you would have to submit the application within the first month of your arrival if you want to stay longer.
You will be using the Visa Waiver and are NOT allowed to stay over 90 days. If you stay over 90 days you will no longer be able to use the Visa Waiver. Rule is = 90 days in and 90 days out.
Italy is part of the Schengen area, which consists of 26 European states. US citizens may visit the Schengen area for up to 90 days per six months without any visa. The time limit is for the area as a whole, without any specific limits for individual states. US passports are stamped both when entering and exiting the Schengen area. Normally there is no passport control when travelling between Schengen states (remaining in the Schengen area) and passports are not stamped.
When first entering the Schengen area you will get an entry stamp. This will not explicitly state for how long you may remain in the area. Without any visa or residence permit the entry stamp will imply leave to remain for 90 days. When you exit the Schengen area you will get an exit stamp and the clock will stop. (Any day at least partly spent in the Schengen area will count as one day.)
If you reenter the Schengen area less than six months from your first entry, the clock will start again, but will not be reset. Your new entry stamp will imply leave to remain for what is left of your original 90 days, not 90 additional days. You may exit and enter the Schengen area several times per day if you wish, but you will still not get more than 90 days per six months.
To remain beyond 90 days you will need authorisation from an individual Schengen state. The procedure differs between states, but a national long-term visa or residence permit allows for side trips to the other Schengen states. If you come to Italy without a visa you will normally not be allowed to extend your stay beyond 90 days. Before you go you should apply for a visa at the Italian embassy or consulate serving the area where you live. In Italy you should obtain a residence permit on foot of your visa.
Depending on the circumstances being caught overstaying may result in just a warning, but you may be fined or even prosecuted. You may also be excluded from not only Italy, but from the better part of Europe for years.
It doesn't work that way. Depending on where you're from, you may or may not be able to enter Italy for up to 90 days without a visa. If you are from somewhere like the US, Canada or Australia, you do not need a visa to visit as a tourist. If you are from one of many other European countries, you can live and work in Italy without a time restriction, but you will have to report your presence and file appropriate paperwork. You can find out whether you need a visa to visit on the Italian Ministry of Foreign Affairs website: http://www.esteri.it/visti/index_eng.asp
Either way, if you are not European you need to leave not only Italy, but the entire Schengen zone for 90 days before you can return. Just going to another country and returning immediately is not acceptable. There is no visa that will allow you to extend your stay as a tourist. If you qualify as a legitimate student or for an elective resident visa, you might be able to get a visa that would allow you to stay longer than 90 days. If you are from Canada, Australia or New Zealand, you may be able to get a working holiday visa that would allow you to stay beyond 90 days and do limited work; this is not available to US citizens. However, with the very high unemployment rates, finding a job would be problematic.
Overstaying a visa is a serious offense which can get you deported and having your passport marked to prevent re entry into the Schengen Zone for years.
