I think they are grey.
Immigration may be mentioned in the Bible, but the only exodus of people from one land to another that was part of a promise from God was to the Jews. Otherwise there are no Biblical examples of people being required to immigrate as a matter law from God. There is certainly no command for Christians to follow either. So that doesn't apply to somewhere like the US and Mexico for example.
There's a case to make for self-defense in the Bible and I agree with it, but there's just as much of a case to make for pacifism. It's a matter of conscience and wisdom to know when self-defense should be applied, to what extent, or if it should be applied at all.
Oh sure people have argued against every belief imaginable trying to use scripture. I simply believe from study and the sum of all of scripture, God leaves us enough to never have grey areas. After all God is suppose to be our ultimate authority.
The Bible has a good bit to mention on immigration:

As for the right of self defense ill pull my previous reply out out of a previous thread I created talking about C. S. Lewis's article on why he wasn't a pacifist.

Self defense or the sanctity of life is a natural law just as evident and observant as the moral law.
Natures laws come from God.
Therefore the right to self defense or the protection of the sanctity of life is good within morality and each of those laws comes from God.
What subject more than life is more important to protect?
Otherwise we have no need for laws.
Otherwise abortion shouldn't be legislated.
Otherwise the murderer shouldn't be put to death.
No need for Police either who the lawbreaker is their enemy.
No need for military who battles foreign and domestic enemies.
Laws legislate morality. And morality dictates what we should and shouldn't do on the concept of life.
Matthew 5:18
For truly I tell you, until heaven and earth disappear, not
the smallest letter, not
the least stroke of a pen, will by any means disappear from
the Law until everything is accomplished.
Exodus 22:2-3
2 “If a thief is caught breaking in at night and is struck a fatal blow, the defender is not guilty of bloodshed; 3 but if it happens after sunrise, the defender is guilty of bloodshed.
(This verse above is where the Castle doctrine or 2nd Amendment found roots in.)
Luke 11:21
21 “When a strong man, fully armed, guards his own house, his possessions are safe.
Romans 7:12
So
then,
the law is holy, and
the commandment is holy, righteous and good.
1 Timothy 1:8
We know that
the law is good if one uses it properly.
2 Timothy 3:26

All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness,
Luke 22:36
36 He said to them, “But now if you have a purse, take it, and also a bag; and if you don’t have a sword, sell your cloak and buy one.
Greek word for English sword:
3162. machaira
properly, a slaughter-knife; a short sword or dagger mainly used for stabbing; (figuratively) an instrument for exacting retribution.
Retribution- requital according to merits or deserts, especially for evil.
Nehemiah 4:10-14
10 Meanwhile, the people in Judah said, “The strength of the laborers is giving out, and there is so much rubble that we cannot rebuild the wall.”
11 Also our enemies said, “Before they know it or see us, we will be right there among them and will kill them and put an end to the work.”
12 Then the Jews who lived near them came and told us ten times over, “Wherever you turn, they will attack us.”
13 Therefore I stationed some of the people behind the lowest points of the wall at the exposed places, posting them by families, with their swords, spears and bows. 14 After I looked things over, I stood up and said to the nobles, the officials and the rest of the people, “Don’t be afraid of them. Remember the Lord, who is great and awesome, and fight for your families, your sons and your daughters, your wives and your homes.”
Who gave this command to self defend your family and homes? God or Nehemiah? Was it wrong for Nehemiah to issue this command while doing the work of the Lord?
John 18:37
36 Jesus said, “My kingdom is not of this world. If it were, my servants would fight to prevent my arrest by the Jewish leaders. But now my kingdom is from another place.”
Jesus is making a distinction of two worlds. Heavenly and Earth. Jesus said if his Kingdom was of this world, his servants would fight to protect him.
Jesus shows us that it is never right to fight for the sake of his spiritual kingdom, but that it is right to fight on behalf of earthly kingdoms (when necessary to counter evil and destruction).
Ecclesiastes 3:1-11
A Time for Everything
1 There is a time for everything,
and a season for every activity under the heavens:
2 a time to be born and a time to die,
a time to plant and a time to uproot,
3 a time to kill and a time to heal,
a time to tear down and a time to build,
4 a time to weep and a time to laugh,
a time to mourn and a time to dance,
5 a time to scatter stones and a time to gather them,
a time to embrace and a time to refrain from embracing,
6 a time to search and a time to give up,
a time to keep and a time to throw away,
7 a time to tear and a time to mend,
a time to be silent and a time to speak,
8 a time to love and a time to hate,
a time for war and a time for peace.
9 What do workers gain from their toil? 10 I have seen the burden God has laid on the human race. 11
He has made everything beautiful in its time.
https://freedomoutpost.com/black-ro...-a-time-to-fight-and-now-is-the-time-to-fight
Everything beautiful in it's time including the time of war. Does anything within time take God by surprise? Or does God use everything to still bring about His will?
So if the Law is good, holy, righteous, and all of scripture is God breathed and useful for teaching, rebuking, correcting and training in righteousness. Then everything listed above is good, holy, righteous and good to learn and train from in order to promote righteousness.
Also self defense against evil tyrannical governments is also well explained in John Locke's book called Two Treaties ( scripture is referenced more than 1500 times)
Examples of leaders raised up against tyrannical governments. Moses, Gideon, Ehud, Jepthah, Samson, and Deborah who was praised for their actions in Hebrews 11 Heroes of faith.
Also we have to remember God ordained boundaries for the individual, the family, the church and Government. For example Romans 13 doesn't give permission to the individual, family, or church to be the police or military but only Government. Government has this authority where as God commands the individual and church to take care of the poor. Taking care of the poor wasn't Governments responsibility.
Final words:
Keep in mind this subject I am speaking very broadly and any situation dealing with violence must be well thought through because as a Christian love is the greatest commandment, revenge is wrong, anger is wrong, murder is wrong, to act unjustly is wrong, we are to strive to be the peacemakers. I may speak on this subject as so matter of fact but due the higher calling of the Christian it often falls into the right to conscience for the believer. If the believer feels he is justified then so he is but if he doesn't then he isnt by the sin, lack of faith. "
