According to Scripture and what Jesus said, no, it's not okay to ask to see Jesus. It's not okay to ask for any sign from God.
I posted on this forum about a year or so ago, if it was that long that I have seen Jesus' face in the clouds, big, huge, in the sky. I did not ask for it however. I have seen angels fly above me and their feet were as fire crackers with sparkles coming from the back as they move through the air. I have seen a large angel stand in the horizon of the Sun, as big as the sky, standing, showing me I'm with God in a very bad time of my life. It's not okay to ask for a sign.
Matthew 16:1-4 NKJV
The Pharisees and Sadducees Seek a Sign
1 Then the Pharisees and Sadducees came, and testing Him asked that He would show them a sign from heaven. 2 He answered and said to them, “When it is evening you say,
‘It will be fair weather, for the sky is red’; 3 and in the morning,
‘It will be foul weather today, for the sky is red and threatening.’ Hypocrites!<sup>[
a]</sup> You know how to discern the face of the sky, but you cannot
discern the signs of the times. 4 A wicked and adulterous generation seeks after a sign, and no sign shall be given to it except the sign of the prophet<sup>[
b]</sup> Jonah.” And He left them and departed.
