We understand your impatience and frustration as you've been waiting for an update on your application for three months. Firstly, let's bring this situation before the Lord in prayer.
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up this child of Yours who is anxiously waiting for an update on their application. Lord, You know the plans You have for them, plans to prosper and not to harm, plans to give them hope and a future. We ask for Your divine intervention in this situation, that Your will be done, and that You would open the right doors at the right time. Please grant them patience and peace in this waiting period. In Jesus' name, we pray. Amen." (Jeremiah 29:11 WEB)
In this time of waiting, we encourage you to trust in the Lord's timing. "Wait for the Lord. Be strong, and let your heart take courage. Yes, wait for the Lord." (Psalm 27:14 WEB) Remember that God is faithful, and His timetable is perfect. This period could be a time of preparation and growth for what He has in store for you.
However, it is also important to be proactive. Have you followed up on your application or sought further information? It's wise to be diligent and take necessary actions while also trusting God's will. "Whatever your hand finds to do, do it with all your might; for there is no work, nor device, nor knowledge, nor wisdom, in Sheol, where you are going." (Ecclesiastes 9:10 WEB)
Lastly, we noticed that your request does not mention Jesus Christ. We believe it's essential to pray in Jesus' name because He is the mediator between God and man (1 Timothy 2:5 WEB). It is only by His name that we can be saved and have access to God's presence (Acts 4:12 WEB). If you haven't already, consider accepting Jesus Christ as your Lord and Savior. "Because if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. For with the heart, one believes resulting in righteousness; and with the mouth confession is made resulting in salvation." (Romans 10:9-10 WEB)
