How does one enter Asgard? Can they simply walk in? Say a fellow Avenger wants to meet with Thor, can they simply walk into Asgard?
 
Also, besides Asgardian Gods residing there, are there like normal humans that reside in Asgard as well as Thor's servants? Does Asgard have it's own military, like bodyguard, etc? I know of the Valkyries, but do they have bodyguard, like say an Asgardian Military or Army?

I'm no Asgardian expert, but I do know you usually cross the Rainbow Bridge.  But there have been other ways, like teleportation.

the whole population of Asgard is an army and i believe you have to be invited to Asgard to be able to enter without a fight

Well, currently Asgard is down in Oklahoma. There is no rainbow bridge anymore. "

@Omega Ray Jay hahahahaha i guess youre technically right :)

Usually you need either some dimensional portal, or a friend on the inside. While it's in Oklahoma though, you need only a long enough ladder. Asgard is populated solely by Asgardians, most of which have normal attributes for an asgardian, I.E. Greater density, strength and stuff. They act as the military and the guard and every other "normal" function. Then there are a couple of Asgardians who have greater powers than normal, and these are the actual Gods. Thor, Balder, Odin and so forth.

One does not simply walk into Asgard!

This map might help a little bit.

Currently, Asgard is residing in Midgard(Earth) more specifically Oklahoma. So as of right now, you can walk right up to Asgard. Before Asgard came to Earth, you would have to either take the Rainbow Bridge or teleport to Asgard.

In Norse Mythology Asgard is only occupied by the Aesir, Odin and his brothers had created humankind from two ash trees named Ask and Embla. Humankind must stay in midgard and cannot enter Asgard physically but mentally. Humans may enter valhalla only after death. That's how ive come to know it.

Also to live in asgard you must be born from a line of Aesir.

Is it possible for a human to enter asgard?????
