I've gone to Ho Chi Minh before.

Immigration there is slow though, so have enough time to make it through and make it back through checking in to fly back.

unless the mother and father were married at the time of the childs birth, the father has, by law, absolutely no obligation to support the child. But he also has no rights towards the child.

Everything is up to the mother.

Is it morally great?

No.

But it is the law here in Thailand and there is no consequence to him stopping the pay to the mother. And honestly, if the mother does not let the child go to see the fathers family, I think it is halfway justified.

@Robert ********

yes

There's plenty of vans doing the same route throughout the day. Depending on what time you arrive and what time you need there.

Some even go straight to the UT airport.

and look at your options.

if not suitable for you, there is probably a chance to strike a deal with a taxi if they don't want to do a metered ride this far. :)

If you use a online booking service like 12Go Asia, you can usually choose seats. And sometimes there are seats with amazing legroom for this short trip.

But for you train might be better.

Tuktuks will very willingly take you to the bus station at Nong Khai, where you will find a bus to Udon Thani for sure.

But there are probably taxis too. I did not really pay attention to them though. I was headed for my bus and got jumped by eager tuktuk drivers that may have overpriced my journey just a smidge.

@Nigel *************

Nong Khai does indeed make you fill out this form.

Bring your own pen.

Was there last week.

I thought these were only requirements for a visa exemption?

If you applied for, and got, your tourist visa, you have already shown these things?

I would book as early as you can though, which is 30 days in advance.
