Better to check with immigrstions but I am assuming that you will need to change visas because they will be your legitimate reason for long stay. Some companies will do the application for a work visa and it will be pegged to the company while some may insist that the employee does all the process by themselves. But in most cases that I know, even if you have approval and a new visa from within the country, you will still need to do a border bounce to stamp out of the old visa and in with the new.

If I am not mistaken, if you have a proper visa for long term stay and need to just leave Thailand at the end of each 180 day stay limit, you should mot face any issues coming back in. Just make sure all your stamps are in place, the original visa issued is in your phone or a print out is on hand, then should mot have any issues. It is not like the visa runs of the old days where you try to come back with a new visa exempt stamp. You can stay for the length of your visa but it has to be up to 180 days each time.

If you are a business owner, you can try to use your company to apply for her a digital nomad, work from any where type of visa. Whereby she works in Thailand using online or Internet work, show that she has a steady income from overseas.

To be frank, different embassies in different countries have different requirements so maybe try in some other country. However, another issue may be that income derived from investments may not be too useful to the embassy because even if it shows a monthly profit and you do withdraw it, it may not be considered a stable income.

You wi usually be allowed one extension before alarm bells at immigrations start to ring. It is best to go before your current visa runs out and make the application. Whether you are rejected and asked to leave or not again depends on the officer and or your entry departure history. There is no such thing as legally in any country if you are using tourist visa to stay long term. There are proper long term visas for every situation and some do get away with extending and going in and out and so on. But being allowed to continue doing so whether it is by extending in country or going out and coming back is at the discretion of the officer you face. They can and do have the authority to question and then deny any further extensions or entry if they so deem.

You should obtain the IDP from your home country. This will state the type of vehicles you can drive and so on.

However, depending on the city you wl be staying at, you have to be very careful because motorcycle accidents are very very common in Thailand.

Since you were pulled aside, it will only be a matter of time before a denial comes. Because a tourist visa is what it means. Saying that you have a girlfriend will only be an accepted excuse before one unhappy officer decides that you cannot go in.

My suggestion is to try and get a longer term visa as soon as you can.

@Ben *****

no just had a series of in and outs that seemed fishy. So the immigration just deemed that I should be denied.

If you overstayed, then there should be a ruling on the penalties of length overstayed and so on. Just check it out.

@Ben *****

try asking a visa agent who will know the latest rules and also they can have a look at any stamp of your denial.

For me, I asked a friend to call them and show them and they advised what the proper things I should do and it worked. I was banned from entry for 6 months and also unable to apply for any visa for long stay for 2 years. I went in after the 6 month and was allowed in and stayed out for 3 years. But going through the airport in transit I was still asked to show onward flight. Once I showed it, no problems going in. Try to get professional advice so that the info is up to date.

I think those in this forum are not with Thai immigration though there may be some spies. So the "you" may be misplaced.

And those who contribute to this are mostly using their own experience or knowledge and should never be used as law.

Now back to your question. The statement you were refused entry means that something happened and you couldn't enter Thailand. This probably means that probably have a ban for a certain period and a probation period of another few years where your entry and exit will be closely watched. Regardless of your passport, your biometrics including face photo is already in the system and can be called up.

So in terms of a blacklist, it all depends on the reason for your denial of entry. There have been some who got denied entry and even after 3 or 4 years and a new passport, when they fly in, they get asked a lot of questions and were required to show an exit ticket. (this is my personal experience). But whatever it is, the laws are clear to all, if it has been abused and thus denial of entry is issued, then the person will need to be more careful and check with the laws that have been stated in the immigration website. Laws and rules do keep changing, so just check it out.
