On October 1, 2009 the Bangkok Immigration office moved to Building B in the new Bangkok Government Center.  The Center, on Chaeng Wathana Road, is being built to centralize most, if not all, of the government agencies in Bangkok.

I hope this page will provide some assistance for those trying to find the building, as it is located quite a ways out from central Bangkok.

The only way to get there is by bus, van, private vehicle or taxi.  If traveling from central Bangkok, I suggest taking the BTS or MRT to the Mo Chit station, and then transferring to taxi for the remainder of the trip.  This will greatly reduce your travel time, as it bypasses most of the traffic congested areas in route.  From Mo Chit, it should take about 20 minutes, if not during peek commute times, late afternoon in particular.  Expect a taxi fare of about 100 baht each way.

While it is still quite a ways out from Mo Chit, most of the drive will be on an express way, and it’s the exact same route you would take if going to the old Donmuang Airport.  I’ve created a Google map that shows the route from (A) Mo chit to (B) Thung Song Hong, where the new government center is located.  The road to Building B is so new Google could not recognize it, so the end marker (B) on the map stops just above Building B.  It is the largest white structure in that area, so you can’t miss it on the map.

Below are three enlargements of the map, one showing the Mo Chit area and the left turn onto the express way just before Central Plaza Lat Phrao (huge shopping mall).   The second shows the Thung Song Hong area and its proximity to Donmuang Airport. The third is an even closer look at Thung Song Hong.

Mo Chit Area

From the Mo Chit station you will travel along side Chatuchak Park and veer left at its northern most end.  It is a huge interchange, so the best way to know the driver is going the right way is to make sure the big shopping mall comes into view on your right as you pass it.

Thung Song Hong area and Donmuang

Once on the express way expect about a 15-20 minute ride before exiting to the left.  When making this turn you should look for three landmarks.  Some single story buildings with red colored roofs should be directly to your left as you make the turn.  These are visible on the Google map if you zoom in close.  Another is the big TOT office tower, also to your left.  On the opposite side of the intersection will be the big IT Square computer mall.  It should be to your right as you make the left turn.  The three yellow arrows on the map point to these landmarks.

Thung Song Hong and Government Center

Your final turn will be left onto Chaeng Wathana Soi 7.  This is a very wide and divided road, so it’s easy to spot.  You should see government buildings on either side of the entrance, but unfortunately I did not take note of what agencies they are.

Building B is distinctive in design, so once in view it’s unmistakable.  The building houses numerous government agencies, but there is a sign at the front entrance pointing in the general direction of Immigration, which is on the first (above ground) level and all the way to the left.  If you access the building from the left end, Immigration is immediately to your right after entering.  The interior of this building is quite astonishing, so accessing it from the main entrance is worth doing at least once. If you enter from the end of the building its grand scale will be missed.

If looking for the 90 day reporting office, go past the main information desk, through a door way and into a large room.  There you will see the desk that issues queue numbers, but you won’t need one.  Instead, turn right and walk to the end, make another right and through some doors to the 90 day reporting office.  There, you just walk up and hand them your form TM 47 and passport and get a number.  When they call out your number, go to the desk and pick up your passport and the dated form.  Copies of the form TM 47 are available at the information desk you passed when first entering the Immigration offices.

I got there at 9:30 in the morning and was done in 5 minutes, with only one person ahead of me.  I suspect the wait is much longer if arriving later in the day, but it’s the first time I’ve ever been in and out so quickly.

Below is a link to a map you can print.  It is all in Thai, but should be helpful if you need to show something to the taxi.  In fact, Leo used it for that purpose when we made the trip. I’ve also included a link to a thread on ThaiVisa.com that talks about the move and has several posts in it about how to get there.

Please feel free to add additional information.  In particular, it would be helpful if someone can offer some good landmarks for the left turn onto Chaeng Wathana Soi 7.
