Several decades ago I recon ;-)

Many, many years ago going to Malaysia, I was told I have to pay tax because I stayed more than 180 days in Thailand, didn't matter what kind of visa. I was told I have to return to Surat Thani to get "tax clearance". Although an hour later, a couple of "papers" in my passport sorted the issue as well.

So I recon, the 180 days is not an immigration but a tax issue.

Never had a problem getting a 1 year Non-B in Penang or Kota Bahru.

17 years of Non-B visas and KL refused my visa because of "too many stamps" which is ridiculous :-)

It's perfectly OK to enter ON the date. Done it myself several times. Even left and entered on the "Enter Before" date.

Doesn't work since weeks. They do not answer mails, nor do you get any tickets and their Facebook page is down since nearly a month.

Basically, people trying to scam immigration rules got scammed ;-)

No you can't. The only way to "switch" passport is if you fly in to a country but if you come in by land, you can not switch Passport between the borders.

Without knowing peoples nationality is always pretty difficult to give good advice but if you are an Israeli national, you will not be able to go to Malaysia.

IATA regulations are amazing too ;-)

There are several companies that will sell you a "Ticket" like Flyonward but I heard several people having problems getting their confirmation within the last two weeks and they do not reply to any mails. The Facebook Site is down too. I suppose, people who wanted to scam immigration law, got scammed themselves ;-)

Now contrary to common believe those websites do not sell any tickets, they just sell you a PNR

A PNR is a database record on the airline's computer that holds the information about you and your flights. But crucially it is a separate system to ticketing, which are financial documents.

Many of those on-line companies are generating a Personal Name Register not a ticketed booking, which may fall foul of a very strict interpretation of the rules as the sole purpose is, to avoid compliance to immigration law.

There are other websites where you can print your own tickets, fake tickets. Should you get caught with one of them, you might even be prosecuted for trying to enter a country with a fake document.

The only legal way is to have a valid onward ticket, PNR is not.

You could always buy a 1 year open return, then keep changing dates and finally, use it or refund it. Why scam the system and in the end pay more, if you can use the system and get something for it ;-)
